Seriously, if I switched on the TV and they were showing live footage of an army of fire-breathing pterodactyls machine-gunning people to death on the streets of London right outside my door, I'd be horrified, but not entirely surprised, nor any more scared than I already am. I'd probably just shrug and wait for them to smash the door down. We're so screwed, I don't even know what to worry about first.
