Not sure about this specific example but if you want to take one example and throw out the baby with the bath water than we should rid ourselves of Border Patrol, ICE, and US Customs and Border Protection:
Border Patrol Abuse Articles
US Customs and Border Protection typically get 9 weeks of training, a gun, and a whole lot of power.
See, this is what you do. You take one example out of a million and make your case based on the unusual, the extreme. Not wise, grasshopper. I can make a much bigger case with our 'trained professionals' that do far worse. Smuggling drugs, humans, drug cartel... agents that sell their Border Patrol jackets to drug smugglers so they are not as obvious crossing the desert, US agents paid by the MX drug cartel to allow drugs through the border, agents that take legals and illegals out in the middle of the desert and rape them repeatedly.
Sure you want to stick with that logic of brilliance?
