I don't understand this either....there is case after case in this country where people are proven innocent over the course of the trial. If the standard is as you two suggest, everyone would be found guilty because, afterall, we don't go to trial unless there is enough evidence to convict. Indeed, we do hold people in jail to get information out of them and we do go to trial to hear all the evidence and the testimony so that we may have a better idea of what actually happened. You guys are off base on this IMO.
There has to be probable cause or reasonable suspicion to detain someone.. You can't hold someone in jail "just to get information" They have to have broken a law.. You're wrong about that..
Legally, you're not supposed to be charged with a crime without evidence, and you have to be charged of a crime in order to be arrested.. You can't held in jail without being arrested. They can't arrest you in order to get the evidence.. The evidence has to come first.
And to you, a dead kid doesn't qualify as "reasonable suspicion"? I can go on about countless cases where people are "brought in for questioning" where they are effectively in jail for 24 hours at a time. Is the person given stripes and thrown in a cell? No. That's yet another dubious distinction I'm not sure matters to the points being made.
If the dead kid was killed in self defense, and there was a corroborating witness, who saw it close up, right in front of his door when he came out to see what was going on.. There was not enough evidence to say he wasn't defending himself.. You have to have a strong case in order to restrict someones civil liberties...
When you're brought in for questioning, you aren't dressed out and placed in a cell, or handcuffed, etc..You aren't arrested..And generally it's voluntary..There is a limit on how long they can detain you without charging and arresting you as well..
But the main point being, the police can not arrest you in order to get information, you have to be charged with a crime in order to be arrested..
And Zimmerman was brought to the police station for questioning that night.. Directly from the scene of the incident..
