As I've written to mdorazio I've actually had the full tear gas experience: locked in a cramped bunker, unable to escape, forced to try to talk in a thick fog of it until officers were happy.

I'd rather take that again than a good number of other unpleasant experiences.

Mentioned it in the same sentence as the use of actual guns seems to indicate that you either talk about a different kind of tear gas or that you don't know what you are talking about at all.
