you really can't generalize like this.
I'm not going to say that many police officers have a bias against import cars any more than anybody else - a lot of people have a very well-founded bias against the ricer mentality.

The fact of the matter is that Georgia cops are just poorly trained and poorly paid. Most of them are just stupid. I don't hate cops, but I do have a certain fear of them. It's unfortunate that anyone should feel like they have to fear law enforcement, but I've fought three tickets and won each time because of officer harassment. I think a reasonable person with that kind of history would have the same view on law enforcement officials.
Now, have I been pulled over for shit I was doing wrong? Absolutely.
But none of those left a bad taste in my mouth like the three instances of officer harassment.
