Gun Control & RKBA

based on that, nothing. Assuming the white cops' motives were racist with only that is, well, racist. If you notice, not only are those different individual cops but they are in different departments in different states. The first one is a city cop somewhere in Michigan the second is is a couple of county cops in Washington. If not racism, what?
one rifle is slung, the other is not.
they are edited from two different YT videos
Are the Washington cops aware that open carry is legal?
Was the second one after a publicized mass murder?
Is that the department's standard policy with "man with a gun calls"?
Have there been past incidents of "cop baiting" in that area?
Neither of us know the answers to those questions. For all either of us knows, the result would be the same if it were two black cops and a white guy. Either way, the black guy got his false arrest payday. That was the goal of both of these clowns.

The white guy, I do know something about. That was more than his first cop baiting exercise, so the Ann Arbor PD probably know of his antics and have been briefed on how to deal with them. Chances are the two cops thought "not this asshole again" when they saw him.

Cop baiting works best if there are no ban, but few people know it is legal, banned with obscure exceptions (see Florida) and cops who don't know the law as well as they should. I frankly have a low opinion of these stunts.
