I think this really cuts right to the problem which is two fold, first is racial profiling and the second is the presumption of guilt that is going on. It is the latter which I find really disturbing.

In a better world an officer might stop someone and ask what they are doing and some id, but they must presume that the person is innocent. My favorite quote from my sister (who is a public defender) is "Being a minority is not probable cause." Once the officer has read the id, they should be on their way.
