One guy lights his shoes on fire on a plane and millions of people now walk barefoot through airport security. Now, I can't even carry my bottle of water with me through security, nor can I buy one in the airport and bring it onto the _plane_. And never mind the now impossibility of having only carry-on luggage for any sort of overnight trip: toothpaste, deodorant, hair products, all off limits.
Disallowing these items in carry-on luggage, and the 1hr+ lines in security as _everyone_ debates with screeners about whether they can be permitted to do so, aren't what makes me the most angry. What makes me the most angry is that just a few _dozen_ stupid people in the world have taken action that have made me and _millions_ of other people that much unhappier today and for weeks, perhaps indefinitely, to come. Damn them.
