Or, if you listen to your lawyer and have a shred of sense, you don't talk to the cops at all. They are interested only in arresting you. The prosecutor is interested only in convicting you. None of them give two hoots about your guilt or innocence.
Save your arguments for the judge and jury. Otherwise, keep your mouth shut.
Now that's a stupid system.
Finding the truth should be paramount to 'winning' the case. It's not a soccer match.
Actually, my friend's case does seem like that though. Before she got a lawywer, she giving them everything they wanted and more. They themselves didn't even bother to check. They got pie in the face later at her hearing.
But it shouldn't be that way. There should be a point where, especially if the person is giving the police information an asking them to check it out, the police should be duty bound to collect evidence. Sure it may or may not be a reliable witness, or it may or may not be genuine proof as opposed to fabricated phtoshop, etc. But still, the police should at least look at it to determine.
If the evidence starts to show the person to be innocent and the police have nothing to counter it, why waste taxpayer dollars?
Insane.
In the case in this OP, it might be different. I'm jsut talking generally that the job should be to reveal the truth, not charge the person at all cost.
