On the topic of open or concealed carry. I have done both before my LE days. I prefer a non multilevel retention holster. That is the gun is held in place by friction, no locks, straps or buttons. Now, why would anyone carry in the open with my preferred holster? Would they carry in the open in any area, with any type of holster, possibly be subjected to having their gun stolen and they are injured or killed for it? I enjoy th element of surprise, more than risk of being a victim for my gun.
I am certainly no fan of the crossdraw or the small-of-the-back holster as our New Hampshire posters seem to be.
But the distinction between concealed carry and open carry is essentially another political fiction We The People should not tolerate from our Government.
Anyone who "open carries" can cross the line to "concealed" either accidentally or deliberately with the addition of almost any type of foul weather gear-raincoat, ski parka, sweater.
Most people, given a choice, would prefer to carry concealed for the exact reason you name.
It was in the aftermath of the Civil War when fear spread across the land newly emancipated citizens might choose to exercise their newly granted sovereignty that laws defining a distinction between concealed carry and open carry became popular.
Over a century later, innocent Citizens in the 21st Century still pay for that little political clusterfoxtrot.
The basic principle at stake here is "innocent until proven guilty". Mere possession of a weapon does not in any way demonstrate malignant intent.
Prior restraint in the form of licensing, background checks, and possession laws are, and should be, UnConstitutional.
A few years ago pictures of young adults who were members of the Israeli Defense Force appeared all over the Internet. They were dressed in civilian clothes, were frequently in groups of two or three, and had their fully automatic platform rifles slung casually over a shoulder. The photographs included group shots in ice cream parlors, public pavilions and buses. It is quite a common sight in Israel and arouses no suspicion from the general public or tourists.
That is yesteryears America and I look forward to the day we return to that public attitude.
