Whether she looks like a fool who would do more harm than good waving it around like that is another discussion.

The commies started chanting "keep mo-ving, keep mo-ving" and left the property untouched. No one got hurt. That is all good and no harm, even if they should work on discipline.

It is common in real world CQB to flag the fuck out of each other in good teams with a lot of trust, although I'm not encouraging the average person, private snuffy, or most SWAT teams to start practicing. Sweeping your spouse wasn't remotely appropriate for this situation, and I wouldn't trust either of them anyways.
