Slowly but surely, the West is heading the way of Israel. The Israelis have had to combat terror for so long that it's second nature there.
Israel profiles Arabs...the West criticizes and is slowly moving in the same direction.
Israel built a wall to keep out murderers...the West criticized it and now they're all building walls.
Israel checks purses, baggage at the entrance to movie theaters, malls, trains, restaurants...the West called it excessive, now Europe and America are waking up.
The only problem is this:
In Israel, they know who the enemy is, what he/she looks like, how he/she sounds, what they want and rely on HUMINT to find the bad guys.
The Americans are not sure who the enemy is. Is it a disgruntled teenager, a military psychiatrist, angry punk, humiliated student, strung out individual on antidepressants or just plane loon?
