As someone already mentioned though, you just can't secure everything. If you secure the terminals, then people will wait outside and be targets. If you secure the parking lots, then cars will queue up outside the lot and be targets. If not the airports, then like in Israel they will target malls, cafe's, clubs, movie theaters, supermarkets. If he wanted to kill Jews, he could've killed them in a synagogue or day center too.

True. At least this one did not get on a plane...

This is the best you can do: let every man (and woman) be armed.
