A THUG—plain & simple.
This acorn didn’t fall far from the tree.
I would sue the man for threatening me. Period.
That is how I see it. If I held one of my rifles in my hand, looked at somebody in front of a bunch of witnesses and said “If I put this up your—ha!—your butt—ha ha!—you’ll find out how effective this is!” or “If I put a round up your—ha ha!”, I would expect to have the police stop by and arrest me for brandishing a firearm, making terroristic threats, threatening bodily harm or any of a slew of charges. Why does the Mayor get a pass for it when normal people would not?
