True, but I do remember in my first CCW class 15+ years ago the Denver instructor telling us we can expect to be arrested so that there would be a record of use of a firearm for future reference if it happened again. Can't vouch for that logic, but that's why I offered the <speculation>.
Besides, the arrest may have actually been for something else, like evidence of drugs or dealing or whatever. NED. Not enough data as of now, but I haven't checked for updates yet this AM. Gotta take care of the three Ss. (Sh*, Shower, and Shave, not the other three Ss.)
