He had a gun in the open? Where did you see/hear that? First I’ve heard and if so, that’s a good piece of info.
There are photos of him all over the place with something on his thigh that is not the seat belt or his arm, but black and sort of shiny and could easily be the barrel of a hand gun.
I don’t know how to copy and link stuff on my kindle , but you’ll find info about the gun being visible at gatewaypundit and conservativetreehouse, both of them probably sourced from the star-tribune. I’d google star-tribune Castile gun.
