Dude should have weeded himself from society without killing his animals first. Seriously what the fuck did that wacko expect? All of his animals to fuck everyone up? Like law enforcement was going to let that happen? I mean good riddance but what an asshole for killing his "pets."
And when you trank an animal of that size it doesn't go down immediately. It runs and hides, then you have to find it (hopefully) before it wears off. Way to much time and to dangerous in a populated area.
