The problem with these guys is that they're so hardcore soullessly evil that they scare most of our professional law enforcement. Consider them irredeemable insurgents at war with our way of life while having no respect for anything except the power of coercion.
While the law dictates such creatures deserve a fair trial I sincerely believe well placed Hydrashocks are the best overall solution. A few weeks of one cop's trauma versus a scumbag running rampant spreading misery over years. Kick me off jury selection now (heh heh).
Nightline tonight is about MS-13
