You have a CCW License

So what??
Most CCW courses are basic safety classes, I've seen many I wonder if safety is even taught that well.

Please do not fool yourself into thinking you are trained to fight just because the state issued you a license

When the rubber meets the road, a lot can be going on, and basic training may not save you, I don't know how much training Mr Wilcox had, , and he may have changed the course of the event, but he lost.
