Though experiment: If I were a criminal....

Rather than curse the darkness, I stepped up to the plate, I got extra training from real experts, countless hours, countless rounds fired in practice and drills of all kinds with the various firearms, revolvers, pistols, shotguns, sub guns, rifles of all types....
Certified as an Instructor......
I helped fellow Officers train, trained with JTF, FBI, PONY, etc.....
We all worked very hard and anything taught had to get approved by council and LE supervision, as far as Legality and department regulations.

I brought the same training to CCW too, I wanted everyone to benefit from advanced training.
