This first execution in 17 years was performed by lethal injection because hanging has a bad rep these days. It feels too Wild West, though it is carbon neutral. And electrocution has been on the outs because I imagine the environmentalists were furious the electricity was coming from coal power plants. (Don’t quote me on that.) I mean, if you’re going to turn a guy into a shish kabob, don’t use dirty energy to do it, okay? Maybe he could pedal a bike that powers his own murder. That’s eco-friendly. Or how about death by a wind turbine? I’m sure if you got a guy close enough to one of those things, the blades would knock his head clean off. That would be completely environmentally sustainable and fun for the whole family.
