Imagine if we knew the general look of a terrorist, and didn't focus our resources properly to go after a terrorist.
For the people who believe profiling is wrong, you have blood on your hands.
If you are a Middle Eastern man in your middle teens to late 40's, you have the same look as a terrorist. You should be mad as hell the people that look like you are willing to blow up planes in the name of Allah, not at the rest of us who recognize the look of a terrorist.
Deal with it.
