Damn straight. Raised rural I was taught that a gun came out only when you either transporting it or planning to do business with it. You do not brandish it around in a store to ‘prove a point’. You may end up proving a different point than you intended.
We used to walk around with them strapped to our hips and hanging from saddle scabbards.
Scared sheep from a slung rifle are idiots.
Where in the story do you see where he brandished the rifle?
Apparently you have not a clue as to what the word "brandish" means especially when referring to a gun.
1 : to shake or wave (as a weapon) menacingly
2 : to exhibit in an ostentatious or aggressive manner
He had it slung over his shoulder according to the story and the police said he was legal.
He didn't "brandish" it.
And your reaction is why the gun grabbers can get so much traction with their "concern trollage" try not having such a knee jerk reaction and think it through.
He wasn't menacing or brandishing or any other thing. He was doing what the 2nd Amendment gives him the right to do, keep and bear arms!
