But we shouldn't fight it by suspecting anyone and everyone. That's like suggesting that we should burn down entire villages, just because we can't be sure which of the local is or isn't an insurgent.

Does people carrying bullets constitute everyone?
If he'd come from North America with a balaclava, copy of the hackers handbook, candy box featuring a picture of David Koresh and a bullet do you think he wouldn’t have been searched and added to a watch-list?
The population of people traveling to countries populated by terrorists and carrying suspicious articles is much smaller than the general population. If we allow the government to conduct any anti-terrorist programs at all, it makes sense to employ such coarse filters to narrow down the number of people they keep an eye on.
Unfortunately there's no way to conduct surveillance only on guilty people.
