Correlation and other jailhouse myths.

correlation  (ˌkɒrɪˈleɪʃən)
— n
1.	a mutual or reciprocal relationship between two or more things
2.	the act or process of correlating or the state of being correlated
3.	statistics  the extent of correspondence between the ordering of two variables.  Correlation is positive or direct when two variables move in the same direction and negative or inverse when they move in opposite directions

There is generally an inverse relationship between the amount of shit you, as a prisoner, may talk and the amount of pants you are wearing while waiting in the nurse's line. This is a correlation. The two phenomena (shit talking and pantlessness) are related, though this doesn't necessarily imply causation. I will bet however that shit talking does have a causal effect upon the state of your pants. So stop talking smack and threatening nurses and you'll be allowed your clothes. 

Miranda Rights:

Everyone who's seen any cop procedural drama knows the miranda warning, or the hollywood version of it. You have the right to remain silent, etc etc. I'll tell you now that odds are you will not be read your Miranda warning if you are arrested. This is because in 90% of cases I don't give a damn what you have to say. If anyone bothered to actually understand what the warning said they'd see that it's related to interrogation, rather than just being arrested. Actually, these guys did a pretty sweet job of explaining this: http://www.cracked.com/article_18385_7-bullshit-police-myths-everyone-believes-thanks-to-movies_p2.html

Arrested for No Reason/Bullshit

This might come as a surprise to you, but depriving a man of his innate freedom isn't easy. There is a tedious amount of paperwork, and a chain through which all arrests have to go through before I'm allowed to leave jail. If you get arrested, you may notice that your arresting officer is annoyed. He might be annoyed with you, if you're a dick, but likely he's annoyed at the 1-3 hours of paperwork (unavoidable paperwork) you just forced him into. Once you're actually in jail, he has to justify his arrest to a detached review staff operating in some other building somewhere, to a jailhouse administrator, usually a sergeant who specializes in arrest policy and elements of offenses under the state penal code, and then a magistrate, all before you can even think of leaving the building. There's a joke that criminals tend to be released before the officer has even finished the paperwork. While this is exaggerated, the truth is criminals are usually processed through and are just waiting for the officer to finish the paperwork so they can leave. So it's a stretch to claim that an officer is willing to put up with this tedium for shits and giggles, or because they don't like you.
