Too much work. A live burial would be much simpler and less messy.
A truck with dual fuel tanks, some chain, and a long, open asphalt highway such as those that run through the desert would be all the tools needed for a fitting punishment.
Is this a dragging or a flambe? Either way, I like my way better. You have to bury them anyway, so live burial kills two birds with one stone (plus it's cheap). No specialized equipment or personnel needed - just someone to add sedatives to the food and someone to plastic-tie and move the condemned into the pine box.
I agree with the chains part........but they should be used to restrain these TCBE savages to steel posts and then roasted alive with a blow torch, S.L.O.W.L.Y, until dead. I’m sure there would be a few that could/would perform this punishment... myself included. send ‘em to hell the most painful and agonizing way imaginable.
