Look at post 53 also here is the link I posted in that thread. http://www2.timesdispatch.com/news/news/2011/dec/03/4/teen-homicide-suspects-had-felony-convictions-ar-1510369/There seems to be a common theme espoused within this thread's posts. They mostly seem to be concerned with a bad guy taking away an OC'rs weapon. That may be a legitimate concern.
Is it possible that a bad guy might walk up and take an OC'rs gun out of a LIII retention holster? Maybe - but probably not and probably not without a struggle. Add to that, that so far in the many, many threads that have covered this topic no one has yet to produce a single case where a bad guy took a gun away from an OC'r anywhere.
That said: There are a variety of holsters that sport Level III retention. I own one made by Blackhawk. I'm here to tell ya that if you don't know what you're doing you aren't gonna get that gun out of that holster. A bad guy certainly isn't gonna be able to do it without knowng how. Point being: A wise man who chooses to OC will at the very least get a retention holster and get training in how to retain it if necessary.
But as we all know, being wise is not a universal quality within the human race.
And wise or not: Open Carry isn't about being wise nor whether or not it is the best strategy for self defense. OC is about the right to keep and bear arms and that right not being infringed. It's about choice - a choice the founders protected by enumerating it within the 2nd Amendment; a choice that has been taken away for many reasons, in contradiction to the prohibition of the government from doing so. Most, if not all of which, boil down to the control of law abiding responsible citizens. They have nothing to do with crime (we all know that gun control doesn't stop criminals from getting guns) or the bogus argument of safety.
More people need to remember that: OC is about being able to exercise a natural right enumerated in the very foundation of our system of laws. Whether or not one chooses to exercise the right is irrelevant. Having the right is all that matters.
