Ayoob; San Antonio Texas PD....
Years ago(5/6) Massad Ayoob wrote about a young police officer who was too timid & risk adverse in training. He was under review & his instructors/field training officers advised that he be separated from the PD(San Antonio TX) but the dept was short-handed.
A short time later, the officer was attacked & beaten by a pack of thugs. The group took his weapons then killed him with his own sidearm.
The point is that you can't be risk adverse. If you open carry, be ready to defend against gun grabs.
