Zimmerman not guilty.

Whether or not they teach ID is a cosmetic difference. Pedagogical differences are what counts, and they're minimal.

In my county, we have public schools, private schools, magnet schools, Catholic schools, and Montessori schools, in addition to all the home schoolers. The county sets standards for the public schools, and can regulate to some extant the others but they are for the most part free to teach how they like. The quality of the public schools varies greatly, so much that property values of homes are affected by the school district they sit in.

As for the rest, you're stuck on technicalities which doesn't really have anything to do with what I'm talking about. How it should matter that different agencies focus on different things is quite beyond me when the issue is cultural influence.

But just to get things straight: it is your opinion that there is no influence whatsoever, and that each US police department exists in a vacuum?

I don't think anyone is arguing that there is no influence. But you don't seem to understand how jurisdiction works in this country. Training and requirements for federal officers differ greatly than, say, the Chicago PD.

And that US institutions popped out like daisies, and have few or no connections to US culture?

This is the problem with your thinking. What is "US culture"?
