How would you react?

A friend posted a link on Facebook to a video on racial profiling.  I couldn't figure out how to post it here, but there's the link.  I was shocked at the reactions of others and shocked at my own.  There's a part of me that thinks this video can't be true, but I can't think of a real argument to say it isn't.  If you have time (4:41 minutes), give it a look.  I'd like your opinion.
