Does anybody think the problem is the law that allows guys like Foster to carry handguns? It's lucky that he didn't kill the two cops. I've never heard of a drug raid where the cops DON'T yell "Police!" when they bust in - - what's the big secret? You think the cops WANT to get shot?
Now as far as police intimidation of witnesses goes, that is just a crime, it's obstruction of justice and it doesn't matter who does it, the cops, their union or their mommas. How the hell anyone can get away with an obvious attempt to dissuade a witness from giving evidence in court, even if it's evidence in support of a serial killer, is beyond me. What kind of law enforcement do they have in Ohio anyway? That's one giant step towards a police state, IMHO. It's gotta be squelched right at the start, firmly and decisively, in a way that no cop will even THINK of it in the future.
