Sad but true, the police and the DHS will be about as useful as teats on a Hillary in preventing American deaths. They are more of a clean up on aisle 9 team.
Any fight against these people will be from an armed and polite populace.
My view is most of the time LE (and civil govt in general) creates the mess on aisle 9. Their solution for cleaning up always involves loss of liberty.
Yes, HOPEFULLY our armed and polite society will step up...
