This isnt about a retention holster but they do "help". This is about a thug deciding that he wanted his gun. The end result would likely have been the same ( retention holster or not). If a person wants to mitigate this sort of thing.. dont make yourself a target. The idea that violent predatory thugs are scared of any yahoo carrying a gun is simply false. Thugs commonly assess the person and rank them based on how formidable and alert they seem. A gun on the hip ( in and of itself) does little to bolster that ranking. Its not about the gun, the gun does not make everyone a hard target. This sort of crime is often about risk vs gain vs effort vs consequences. If you are being eyed by a thug, its usually beneficial that they perceive risk and effort to easily outweigh the gain. Even then, a criminal may take the risk in spite of all the other factors. No matter how you look at it, the lone citizen is at a substantial disadvantage in a busy public space that they do not control. If a person is going to OC, I would hope that they are on their [A] game.
