Facebook removed two posts from a Republican member of Congress representing Louisiana on Tuesday in which he threatened demonstrators against police violence, suggesting he would shoot and "drop any 10 of you where you stand" if they took to the street armed.

"If this shows up, we'll consider the armed presence a real threat," Rep. Clay Higgins, a former law enforcement officer, posted Tuesday on his personal, verified Captain Clay Higgins Facebook page along with a picture of an armed Black militia group that has protested the police killings of Breonna Taylor and George Floyd. "We don't care what color you are. We don't care if you're left or right. If you show up like this, if We recognize threat... you won't walk away."

[He] made no reference to protesters turning violent, but instead suggested their mere armed presence would be considered a threat.

Louisiana is an open-carry state, meaning a permit is not required for someone to visibly carry a firearm in public.

Higgins did not consider the right-wing "militia" armed with AKs who showed up to observe the Black Lives Matter protests in Lafayette Louisiana as a threat. The NFAC showed up armed but peaceful in response to the right-wing militia presence and that shook up Mr. Higgins.
I'm sure he also wasn't threatened by the Jan 6th mob who literally showed up in "his neighborhood" not only "threatening" violence but perpetrating it.
