Is it illegal to run away from a police officer in a way that provokes them, in the US?
<p>So I know this is very silly and obviously hypothetical, but I've wondered about it for a while.</p>

<p>Let's say you aren't doing anything (else) illegal, you don't have anything illegal on you, and you don't have any warrants for your arrest or anything. And let's say we're talking about this occurring in the USA.</p>

<p>Now let's say there's a cop on the street and you're walking by him, and suddenly you yell "Oh shit! The police!" and then bolt down the street in the opposite direction, such that they clearly heard you say that and see you running.</p>

<p>Is that illegal? First, assuming that the cop <em>doesn't</em> chase you. Is it just illegal to "provoke" a cop like this?</p>

<p>Then let's assume the cop is intrigued and does chase you. Is it illegal to keep running? Would it make a difference whether he yelled for you to stop or not?</p>

<p>Bobstro gave the practical answer, that it's a stupid idea for many reason.</p>

<p>This is for the US in general, states may have laws that say otherwise.</p>

<p>It is not illegal to provoke someone or a government official (police), it's done all the time in protest (not riots). </p>

<p>It is not illegal to run from a cop who has not detained you in any way, or has not issued an order to you. The U.S. Supreme Court  has made clear that people not suspected of criminal activity can ignore a police officer who approaches them.  <a href="http://thefreethoughtproject.com/state-supreme-court-wisconsin-drivers-ignore-cop-knocking-car-window-drive/" rel="noreferrer">Wisconsin</a> has even said, that even after a police officer knocked on your window, you can still leave. However, it <strong>may</strong> give probable cause, especially with the statement of "Oh shit! The police!"</p>

<p>It <strong>IS</strong> illegal to run from a cop who has detained you or issued a lawful order. The order "STOP" is a lawful order, and from that point on, you are committing a crime if you do not stop.</p>

<h1>Short Answer</h1>

<blockquote>
  <p><strong>The facts described by the OP do not, alone, constitute a crime.</strong></p>
</blockquote>

<p>However, they are likely to begin a chain of causal events <em>that can lead to a crime</em> following a natural sequence of escalatory stages if the "suspect" does not change their behavior to stop the progression.</p>

<p>Let's analyze how this might happen...</p>

<p><hr></p>

<h2>Analysis</h2>

<hr>

<h3>Stage One: "Reasonable Suspicion"</h3>

<p>Your behavior:</p>

<blockquote>
  <p><em>[saying] "Oh shit! The police!" and then bolt down the street in the opposite direction, such that they clearly heard you say that and see you running.</em></p>
</blockquote>

<p>might give the officer "<strong>reasonable suspicion</strong>" to believe you have committed a crime. </p>

<p><strong>Reasonable Suspicion</strong> is defined as any "articulable reason" to suspect you have committed a crime based on the facts and rational inferences from those facts based on the officer's experience and judgment. In other words, anything more than just "a hunch." In this case, the officer might decide your behavior meets that threshold and would likely be affirmed by the court because your described behavior is more consistent with criminals than non-criminals. (See <a href="https://law.stackexchange.com/a/498/248">this question and answer</a> for more details.)</p>

<hr>

<h3>Stage Two: "Detainment"</h3>

<p>With that <strong>reasonable suspicion</strong>, the officer has lawful authority to "<strong>detain</strong>" you for further questioning and investigation to determine if there is "<strong>probable cause</strong>" to conclude you have committed a crime and then, if so, to arrest you.</p>

<hr>

<h3>Stage Three: a "Lawful Order"</h3>

<p>If the officer decides to <strong>detain</strong> you, he can issue you a "<strong>lawful order</strong>" to stop running away simply by saying "Stop! Police!" loud enough for you to hear it.</p>

<hr>

<h3>Stage Four: a Crime</h3>

<p><em>Willfully refusing a lawful order by a peace officer.</em></p>

<p>If you continue running away after being issued a <strong>lawful order</strong> to stop, you have committed a real crime and can be lawfully arrested at that time and successfully prosecuted for that alone despite the absence of any other criminal offense.</p>

<p><hr></p>

<h2>Conclusions and Recommendations</h2>

<p>In general, it is wise to avoid unnecessarily provoking the police. Or giving them <strong>reasonable suspicion</strong> to <strong>detain</strong> you if you can avoid it. It is very difficult to imagine any set of circumstances where it is prudent to "run" from the police. You should consider running from the police extremely serious and dangerous behavior.</p>

<p>There's a video of a night-time police stop of a 17-year-old driver in Michigan for flashing the officer with high beams. The officer initially states his intention to only give the driver a warning.  Unfortunately, the kid decided to play the "am I free to go?" line rather than cooperate, and the officer decided to escalate the situation. At one point, the officer pulls the kid out and attempts a take-down. The kid panics, breaks free, and runs. The officer pursues and eventually kills the kid with his gun. Here's a <a href="http://www.lansingstatejournal.com/story/news/local/2015/06/16/press-conference-eaton-guilford/28801761/">link</a> to news coverage.</p>

<p>Regardless of whether the actual act of running is legal, this case suggests that it could cost you your life.  The officer in this case faced no criminal consequences from his actions.</p>

<p>[edit]The question(s) do not take into consideration of outside factors, such as the chase itself. The answer to the question of legality surely depends on jurisdiction, which is not provided in the hypothetical situation as described.</p>

<p>Quite a few states have laws against things like "interfering with a peace officer" or "obstructing a peace officer".</p>

<p>This action might or might not fall within that statute, but there's enough variation in wording between states that it's impossible to say in general. It can also depend on some other parts of the situation, such as whether the police officer in question is busy doing something else at at the time or not.</p>

<p>In particular some states' laws include wording about the obstruction involving violence toward the peace officer, such as (<a href="http://tornado.state.co.us/gov_dir/leg_dir/olls/2013TitlePrintouts/CRS%20Title%2018%20(2013).pdf">Colorado</a>):</p>

<blockquote>
  <p>A person commits obstructing a peace officer, firefighter, emergency medical services provider, rescue specialist, or volunteer when, by using or threatening to use violence, force, physical interference, or an obstacle, such person knowingly obstructs, impairs, or hinders the enforcement of the penal law or the preservation of the peace by a peace officer, acting under color of his or her official authority;</p>
</blockquote>

<p>So, in Colorado the judge/jury would have to decide whether (for example) your action could be construed as creating/using an obstacle to the police officer performing his duty.</p>

<p>In Illinois, however, <a href="http://www.ilga.gov/legislation/ilcs/fulltext.asp?DocName=072000050K31-1">the law</a> doesn't include similar language limiting such obstruction to things like violence:</p>

<blockquote>
  <p>A person who knowingly resists or obstructs the performance by one known to the person to be a peace officer, firefighter, or correctional institution employee of any authorized act within his or her official capacity commits a Class A misdemeanor. </p>
</blockquote>

<p>So, in Illinois, there's a lot better chance that you could be convicted, even though your action was relatively indirect and non-violent.</p>

<p>In at least some states, the act of running away has been ruled sufficient to qualify as obstruction but at least as far as I can see, it's usually running away when an officer has approached that person. For example, Nebraska law uses the wording:</p>

<blockquote>
  <p>A person commits the offense of obstructing a peace officer, when, by using or threatening to use violence, force, physical interference, or obstacle, he or she intentionally obstructs, impairs, or hinders (a) the enforcement of the penal law or the preservation of the peace by a peace officer or judge acting under color of his or her official authority or (b) a police animal assisting a peace officer acting pursuant to the peace officer's official authority.</p>
</blockquote>

<p>However, Corey Richter was convicted of violating this law based only on running away from the police:</p>

<blockquote>
  <p>Richter had been staying with his grandmother who, on October 20, 1986, asked the police to remove him from her home. Officers Mike Brunz and Douglas French, both in uniform, went to the grandmother's home in a marked police car to so do. As they approached the home, they could hear Richter arguing with and cursing and yelling at his mother. Officer French told Richter they were going to take him to a youth shelter for the evening. Richter ran away as the officers were escorting him to their automobile. Officer French then pursued Richter on foot, but lost sight of him. The officers found Richter approximately an hour later near his grandmother's home. Upon seeing the officers Richter started to flee again, but returned peacefully after his mother yelled for him to stop. No physical restraints were ever placed on Richter, nor did Richter ever resort to force.</p>
</blockquote>

<p>I'd rate it as extremely risky at best. At best, you'd probably be arrested and spend a few days/nights in jail, but not convicted. On the other hand, it could pretty easily result in a conviction, and the fact that the state's law has wording about using violence (or similar) wouldn't necessarily provide you with  any protection.</p>

<p>The Supreme Court makes a distinction between walking and running. The Supreme court allows laws to be made against running from the police (<a href="http://articles.chicagotribune.com/2000-01-13/news/0001130134_1_william-wardlow-rehnquist-court-illinois-supreme-court" rel="nofollow">Illinois vs Wardlow</a>), but not from walking away (<a href="https://www.law.cornell.edu/supremecourt/text/392/1" rel="nofollow">Terry vs Ohio</a>). Walk away until you get around the corner. Then start running. If the police drive up to you while you are running, stop running and start walking. If they ask why you are running, say you have a cramp in your leg, but keep walking. If they tell you to stop, you have now been detained for acting guilty/stupid. When you first see the police, make a 90 degree turn to a different direction. Turning around and walking the way you came will get you handcuffed and searched. If something is found, the police will describe to the judge how you saw the police, then turned around and started walking. I know the temperature after dark is nice for a summer walk, but don't go walking after dark. Join a gym. Walking around after dark is not illegal, but you will get handcuffed and searched often. If you're walking in a bad neighborhood, the police will think you're a drug dealer. If you're walking in a good neighborhood, the police will think you're a thief. Please don't hate the police for this because they're doing what the people who live there want them to do.</p>
