Columbine by Dave Cullen:
Eric had been looking into the Brady Bill. Congress had passed the law restricting the purchase of most popular semiautomatic machine guns in 1993. A federal system of instant background checks would soon go into effect. Eric was going to have a hard time getting around that.
“Fuck you Brady!” Eric wrote in his journal. All he wanted was a couple of guns—“and thanks to your fucking bill I will probably not get any!” He wanted them only for personal protection, he joked: “Its not like I’m some psycho who would go on a shooting spree. fuckers.”
