“He didn’t want to be accused of racial profiling”
Therein lies the problem. We MUST racially profile. Common sense dictates that we do. That does NOT mean we harm others, that does NOT mean we take their rights away. That simply means we check to be sure “they” are not a problem.
When ‘something’ is shown to be the cause of all, or even most, of terror, it makes sense to be wary of that ‘something’. If you get bit by dogs throughout your life, that doesn’t make you wary of cats.
