We MUST be proactive about our own safety because TSA and Homeland Security only attempt to screen items and not PEOPLE. When airlines are graffitied in their parked state and access to them is unguarded, are we (or those whose employment is within them) to believe those airliners are guaranteed safe? Profiling is a necessity IMHO and those who refuse to do it are gambling with passenger and crew lives on a daily basis.
We already know who is trying to kill us and why - that we cannot protect ourselves from those who fit that pattern is nothing short of ignorant in this day and age. It's akin to knowing lions kill people, but we'll walk among them and see if they attack (because not all of them may be hungry).

Ditto that.
