Are you this dumb? Seriously? If you intent is to kill someone, it is significantly easier to do with a gun than with a fucking truck. If you miss with a truck, you think you can just ask the people to wait a bit while you back up and try to hit them again? How many hours do you think you can get in with one truck vs with one gun? You miss with a gun, it is easy to fire again.

As for a fertilizer bomb, it is not like the Anarchist Cookbook makes it out to be. Lots of people die while making explosives. Many die trying to set them off. How many people die purchasing a gun? How many people die using a gun compared to the number of bullets expended from guns. Going to guess the death ratio is a hell of a lot lower than fertilizer bombs.
