You deal with “no go zones” by GOING THERE. If it’s “no go” because police & others get harassed or worse just for being there, you enforce existing laws with gusto. Legitimate authorities are supposed to legitimately exercise their authority, even if it puts them in harm’s way - ESPECIALLY if it puts them in harm’s way. These “no go zones” are forming because they’re getting away with it. If the offenses seem orchestrated by non-citizens, then you get the National Guard et al in there if need be (I understand “Posse Comitatus Act”, which is not meant to stop our military from addressing invaders appropriately).
Yes, you’re right, but how well did that work in Ferguson? To do what you’ve said you have to have the willpower - and the legal cover - to do so. How have Trayvon and “The Gentle Giant” helped law enforcement to have the willpower and legal cover to handle “no-go areas”? We’ve got an OFFICIAL “no-go area” along the Arizona border. It’s just been handed over to the Mexican coyotes to have their rape trees, etc. That fact alone tells us that as things are right now we do NOT have either the guts or the legal fortitude to handle large numbers of people who want to live by laws other than this country’s. That is just a fact, and we HAVE to deal with it.
Trump is right to say we have to figure out how we can even handle such a situation before we allow it to happen.
