What comes first: the arrest, or the charge(s)?
<p>Forgive me if this seems like an asinine question, and please feel free to be as pedantic as possible if answering. I'm working on data modeling a piece of software and it's relevant to my data structure design. I appreciate any insight that can be offered.</p>

<p>I am of the opinion that the <strong>charge(s)</strong> must exist before an arrest is made, i.e. one must be charged (by the police, or by another agency with the authority to make arrests) with something before they can be arrested, i.e. one is arrested <em>on charges</em>. I also realize that the charges can and do sometimes change (or disappear, for that matter) after the arrest, but for my purposes that is irrelevant. I am strictly concerned with the circumstances leading to an arrest and jail.</p>

<p>The question also extends to summons and warrants. Charges <em>must</em> exist before one can be summoned or a warrant for the arrest issued.</p>

<p>Am I looking at this the right way? </p>

<p>Thanks in advance to anyone willing to take a few minutes to help me sort this out.</p>

<p>It can go either way. If detectives have been working to build a big conspiracy case against you, they might get charges filed before they roll up to arrest you. If a cop catches you mugging someone, they'll arrest you on the spot and charge you later. </p>

<p>Different jurisdictions have different rules on this, as well as different concepts such as "detained without charge" and "assisting the police with their enquiries". However, just to give one example, in England and Wales <a href="https://archive.is/20120805174930/http://www.statutelaw.gov.uk/content.aspx?LegType=All+Legislation&amp;title=Police+and+Criminal+Evidence+Act+1984&amp;searchEnacted=0&amp;extentMatchOnly=0&amp;confersPower=0&amp;blanketAmendment=0&amp;sortAlpha=0&amp;TYPE=QS&amp;PageNumber=1&amp;NavFrom=0&amp;parentActiveTextDocId=1871554&amp;ActiveTextDocId=3416535&amp;filesize=4138" rel="nofollow noreferrer">s.24 of the Police and Criminal Evidence Act</a> explicitly permits arrest without warrant (and hence without charges) in some circumstances.  <em>Habeas corpus</em> restricts the right to detention without charge: in Britain the police usually have 24 hours after arrest to either charge you (with the consent of the CPS) or release you without charge, in which case the arrest need not be revealed on employment applications, for example.</p>

<p>Incorrect. A warrant may be issued for a search of your apartment based on reasonable suspicion by the police that a crime has been taking place there. This could be, for example, from their observing you and an informant they believe to be giving them proper information. </p>

<p>They take that info to the judge and the judge approves the warrant. They come, they search, they find all of the drugs, and then arrest you. You have not been charged with a single thing yet. In fact, depending on the timing (weekend?), you may be released and have to report back or you may be detained until your arraignment which occurs before a judge. At the arraignment is when you are charged. </p>
