I agree with what you are saying and it seems you read something about this article that had more information on it than what I read.
I am a Federal LEO myself, I don't know for sure, but I think that Maryland State Troopers are always on duty. The trooper had all rights to do step out of his personal car and make the stop.
I know that he should have had his badge out and not his gun and identified himself upon exiting his vehicle.
I know what a weapon is used for I have been trained as a MP in the Army and by the Federal Government at FLETC. It was unjustified in that situation.
Mind you I would never be in this rider’s situation, as I never ride reckless as this guy was. I was simply stating, from the article I read and the little bit of the video I saw, that if I saw a guy step out of a personal vehicle drawing a weapon of any kind (after I was riding like an @$$hole or not) and the first words out of his mouth are not POLICE. My first thoughts would be to get out of there.
I know my hands would have been in the air as soon as the weapon was place in the situation.
