Freeze!

I agree that the whole "moving gets you shot" clause can seem a bit easy to accidentally fuck up, especially if you grab them while they're already holding down a move key. Why not disallow movement, or have a toggle like the previous person said, and just display the "Hoss Taege struggles to move" text, or maybe add something along the lines of "Hoss Taege looks like he wants to move, but is too afraid to try to break free!"
