A now dead troll comment suggest that he should shoot first. While I don't agree with this at all, this is almost certainly going to happen and sooner rather than later. See right now in Ferguson, with the random cop killings.

People break in different ways. Some break inwards, others outward - and no this isn't a gun issue. Palestinians have figured out that you can kill people with a car - heck half an ounce of flour in an envelope will cause massive panic and workplace disruption.
