Drawing a gun on someone suspected of stealing a duffel bag, with no weapons showing? Great example of a responsible CCW holder.
As the holder of a CCW permit, there is no legal duty to intervene. In fact, intervening exposes you to far greater legal jeopardy, as shown in the OP.
I carry a gun to protect me and mine from death or grave bodily injury. Not to prevent someone from stealing a homeless guy's duffel bag.
