Here's a great example of how the police have failed to live up to 'serve and protect'.
Here is an EU police car. Note it's bright colours to be easily spotted. Dare I say this car looks friendly. http://cdn1.blog.powerblocktv.com/wp-content/uploads/2012/10...
Now, here's a US police _interceptor_. The front grill looks like it's ready to ram me. http://s3.caradvice.com.au/wp-content/uploads/2011/08/2011-F...
The MRAP's to your point only exacerbate existing problems in the US police state. I don't see why the police (and some folks here) can't see that.
