Can a civilian legally take any action against a police officer if they witness the officer violating traffic laws?
<p>I saw <a href="https://www.youtube.com/watch?v=pKMbYx_b5x0" rel="nofollow noreferrer">this video</a> where a civilian manages to pull over a police officer for speeding. I doubt pulling someone over as a civilian is legal, strictly speaking, especially since the guy had to speed himself to keep up with the speeding officer. I know there are some situations where officers speed within their right, even without emergency lights, under certain circumstances. </p>

<p>But I was interested, for technicality sake, in learning what legal rights civilians have if they wish to take action against an officer they believe to be needlessly violating traffic laws <strong>for personal benefit</strong>. Lets say someone witnesses an officer turn on their lights and speed to pass traffic, then sees them pull into a doughnut shop a few blocks later and want to report that kind of misuse of power. </p>

<p>I know one can "make a complaint" but I'm wondering if there's generally any legal obligation for these complaints to be taken seriously, and if there's any feasible way a driver could validate the encounter. If a civilian takes a video of the officer speeding he'd probably be admitting to distracted driving, a crime in itself. If he looks at an ID number on the car and claims that was the car, it seems like it would be the civilian's word against the officer's. Wouldn't that just go the officer's way?</p>

<p>Legally speaking, do civilians have any right to apprehend an officer for a traffic violation? I've heard of civilian arrest but I know little about it. I'm curious to know if what this civilian in the video did (asked the officer to slow down) is even legal if he managed to stop the officer without speeding to do so.</p>

<p>Furthermore, even with evidence, is there any way a citizen could ensure that legal action be taken against the officer for a proven traffic violation? Beyond reporting it to the department and hoping for the best?</p>

<p>A prosecutor is under <a href="https://en.wikipedia.org/wiki/Town_of_Castle_Rock_v._Gonzales" rel="noreferrer">no legal obligation to press charges</a> (and police have no affirmative duty to enforce the laws on the books) ever, even if there is blatant and clear evidence of murder, let alone a traffic violation. </p>

<p>Usually, there is absolutely no way to compel charges to be brought against the offender (with a handful of states providing an exception where one can seek the appointment of a special prosecutor to investigate and prosecute if the circumstances warrant that would never be invoked for a mere traffic offense). Very few states allow anyone other than a prosecutor (or sometimes in minor cases, a law enforcement officer) to bring criminal or quasi-criminal charges.</p>

<p>Of course, if compelling evidence of a violation is found and shared with the media, there may be powerful political pressure to bring a prosecution, but how that is developed would entirely depend upon the circumstances. </p>

<p>Still, the relationship between prosecutors and law enforcement is so symbiotic, that prosecutors are loathe to press charges against law enforcement officers in all but the clearest of cases, especially for offenses occuring while a law enforcement officer is on duty in his home jurisdiction.</p>

<p>While this would depend upon state law, most states treat traffic violations as a class of offense different from other misdemeanors and infractions and never authorize a citizens arrest for a traffic violation. Normally, only law enforcement officers can stop and cite people for traffic violations that aren't actually misdemeanor crimes.</p>

<p>For example, in Colorado, true traffic infractions are defined as civil matters for which someone may be stopped and subjected to a citation but not arrested (even by a law enforcement officer). <em>See</em> Colorado Revised Statutes § 42-4-1701(1). In Colorado, only more serious traffic offenses (e.g. hit and run) are crimes subject to arrest. In the case of a traffic offense which is a crime (probably not speeding), the general rules applicable to citizens arrests would usually apply.</p>

<p>This is governed by state law, though it originates in the medieval obligation to join the arrest mob and is a long-standing part of common law. <a href="http://www.leginfo.ca.gov/cgi-bin/displaycode?file=833-851.90&amp;group=00001-01000&amp;section=pen" rel="nofollow noreferrer">California Penal Code section 837</a> says that</p>

<blockquote>
  <p>A private person may arrest another:</p>
  
  <ol>
  <li><p>For a public offense committed or attempted in his presence.</p></li>
  <li><p>When the person arrested has committed a felony, although not in his presence.</p></li>
  <li><p>When a felony has been in fact committed, and he has reasonable cause for believing the person arrested to have committed it.</p></li>
  </ol>

On the other hand, Washington has no citizen's arrest statute, and relies on the common law tradition (which is <a href="http://apps.leg.wa.gov/rcW/default.aspx?cite=9A.04.060" rel="nofollow noreferrer">statutorily incorporated</a> into the law), which means that it's not clear what the boundaries are. The Department of Licensing sets for a position <a href="http://www.dol.wa.gov/business/securityguards/docs/citizenarrest1.pdf" rel="nofollow noreferrer">here</a>, which is relevant for security guards (who need to know if they can do it). In <a href="http://courts.mrsc.org/appellate/024wnapp/024wnapp0437.htm" rel="nofollow noreferrer">State v. Gonzales, 24 Wn. App. 437</a> affirmed that a citizen has the right to arrest for a misdemeanor committed in their presence. There does not appear to be any right to arrest for ordinary speeding (which means that the police also cannot arrest you, though there are criminal types of speeding such as reckless endangerment).</p>
