Yes the couple looked ridiculous and overreacted. However, LOL at the mainstream media portraying this as a white couple pointing guns at "peaceful" protesters.

A mob of over 100 people forced their way through a locked gate into a private neighborhood, then marched the streets angrily shouting, "Eat the rich!"

This was no peaceful protest, and if you think you wouldn't be scared if that was moving right in front of your house, you're lying. You'd be sitting there with a gun in your hand, too (if you had one). Only difference is that you'd probably stay inside and wait to see what happens next.

Anyway this was a very threatening and inappropriate protest, and nobody taking part should be considered sympathetic.
