Came across Terminator 2 last night on TV. The scene that always amuses me is during Sarah Conner's escape attempt. She's spotted what she thinks is the Terminator that tried to kill her, and fled right back into the arms of the asylum's security personnel. What gets me about that scene is how the security guards/orderlies are so focused on Sarah they seem oblivious to the fellow in black leather with the shotgun striding towards them, at least until he grabs the first one and tries to throw him through that window.
Sure, Sarah's a handful, and even if they'd noticed it wouldn't have helped them any, but I'd have thought one of them would be aware enough to say something like "Sir, I'll have to ask you to leave". Then get thrown through a window.
