This scumbag was caught trying to sell cyanide to white supremacists.
This is the stuff that I fear the most. Some may whine about the dangers of firearms to society and the threat of militant looking weapons with scary accoutrements, but firearms are a poor way to conduct mass killing.
Chemical or biological weapons are not at all hard to get ahold of, or make, and it may not be haji sneaking across the border with stuff like this. It could be guys like this meth head trying to trade 100 lbs. of chemical for a pound of drugs.
