As far as people are concerned, the AR15 is a machine gun because it exists in a fully automatic configuration too. In fact, the full version of the white guy's encounter has the cop pulling showing off his fully automatic AR15 machine gun.
Note: I am not a gun person so I may be wrong in equating fully automatic guns with "machine guns."
The AR-15 is a civilian variant of a military gun. Yes, it can be made to be fully auto and even a few come in full auto variants and yes civilians can own fully automatic weapons. All that said, automatic weapons are ridiculously expensive and require a metric fuckton of ATF paperwork along with a rather large fee to the ATF for every transfer. We are talking $20,000 or so for a single gun, give or take. The type of person who can spend that kind of money on a gun is almost always a collector of some sort and would never put that expensive as weapon in a position to have some cop throw it on the road or some shit like that.
I'm not sure what the relevance of an employee of the state having a fully automatic weapon has? Furthermore, if the employee of the state would have been walking around in his state provided uniform with his state provided badge with his state provided fully automatic weapon I highly doubt anyone would have intervened, especially not to the level shown in the video. More likely the other state employees would have gave him a high-five or a handshake, bitched about their wives for a minute and carried on about their days.
