Any (American) government that wants NOT to get its butt tossed out at the next election won't even consider sending troops to protect mosques (a law enforcement function, thus prohibited by Posse Comitatus) after another significant outrage by the islamist subhumans. Granted, the Feds might well consider coercing state/local gov'ts in sundry ways to send troopers, police, and whatnot to do this task, with the obvious purpose of dodging responsibility for public blame while still, notionally, ''protecting'' public ''safety''.
Please note CAREFULLY that this sentiment neither says nor implies that every follower of islam -- which cult name I refuse to capitalise, deliberately, despite common (mis)usage -- is subhuman.
Some war on terror.
