Attended college in Indiana in the 60's.
The head of the dorm was an asst. dean. I told him I had a pistol and a shotgun. His advice was to keep them in my closet and don't let anyone else know so they wouldn't be stolen.
In Indiana at that time no permit was required if a pistol was open carried, so I'd strap my Ruger Single Six on, and carry my shotgun openly from my dorm room through the campus to my car to go hunting. No one batted an eye.
The following year the dean asked if I would leave the guns at a room near the front desk and pick them up when I wanted to go hunting. Oh, the terrible restriction!
One can only imagine the result today of strolling through a campus like that.
Many years later I was a state peace officer in Queens NY and took a guy into custody for doing the same thing. He was dressed in full camo and walking down the street in the very urban Jamaica section (high crime and drugs) carrying a scoped high power rifle and looking very out of place. As they say in real estate, "location, location, location".
He walked into a store and I questioned him (after removing the rifle from his possession). No ID, no required permit. No explanation as to why he was carrying the gun. I didn't think he was on route to go hunting, at least not for game.
I didn't have the time for an arrest, so I called 911 for backup and handed the collar over to the plainclothes NYPD anti-crime squad guys who responded.
They were glad to get it, "collars for dollars", i.e., overtime for an arrest. And a gun arrest was always a good one on your resume for promotion.
