Surely he would have frozen?

I mean Kallman. Being left to sleep on a bench, drunk, in the snow. He'd have frozen. That was what I expected to be the outcome from that prank, especially as the blurb for the film mentioned 'fatal consequences' - of which incidentally, there were none (unless I nodded off unawares).

Well, he'd have frozen where he was before they moved him too, I guess, but that's beside the point. Not sure that counts as a plot hole, but that bothered me for the rest of the film.
