"I can not imagine that there aren't enough lawyers in New Hampshire that can't file some kind of emergency injunction..."
An emergency injunction? Against what, you bedwetting loser? The guy was just standing there minding his own beeswax, which is, granted, a foreign concept to you, but trust me, that's all he was doing.
To hear you people carp and bleat, you'd think the guy was standing there with a nuclear-tipped surface-to-air missile launcher or a pack of rabid cyborg velociraptors with laser beams for eyes, not a budget model 9mm pistol in a gun show commando holster. The President wasn't going to be coming within 100 yards of this guy, and that in a limo armored against rocket-propelled grenade fire. For Vishnu's sake, Barry was in more danger from birdstrikes on Air Force One than he was from this cat's pistol.
