This topic comes up every so often, and this is the video someone posted last time:
Dont Talk to Police - YouTube
I just posted this on another forum: I watched it a while back, and until then, always thought that in any situation, shooting or otherwise, of course I would just be cordial and cooperative with police. Wrong.
It's natural for a self-defense shooter to think they are in the right. They were there, after all, and they know what happened. Guess what? The cops don't. They show up on the scene, and you're the guy with the gun, who just killed or seriously injured the guy lying in a pool of his own blood.
Chances are, you will get cops who sympathize with you. But, as the prof in the video talks about, the cops' job is to put someone in jail. So even if things are OK on the scene, they may be expected to provide testimony for the prosecution later.
The real eye-opener for me was the fact that anything, yes ANYTHING you say can be used against you. I always thought that meant you shouldn't say anything damning, but no, it means if you say "I was just on my way to Aunt Tillie's to deliver some cookies," a cop will relate this info to a lawyer, and a lawyer will twist it around to say: 1. The defendant told police he was on his way to visit his Aunt Tillie. Why, then did he make a point of stopping to shoot my poor client? Obviously he was well out of harm's way. 2. The defendant told police he had just made the cookies, yet he was armed. Does the defendant really wear a pistol on his hip while baking in his own home? Just how paranoid is this individual? This, combined with the fact he recently rented several violent revenge films, clearly shows an individual who was looking for an altercation, and was determined to find one no matter what.
That's obviously an extreme and silly example, but you get the idea. When they say anything, they mean anything.
Get a lawyer before you make a statement. If you can't afford one, the state will provide you with one. Chances are you have acted correctly, and you'll only get billed for that hour it takes to consult and write out a report.
