I started my LE career in the mid 70s. The "Newhall Incident" was still raw and fresh. It had a profound effect on firearms training in the West. The old slow fire target training was eventually replaced with training more related to real world needs and situations. The phrase "what you do in training, you will do on the street" finally gained acceptance.

During my time in LE we went from shooting 38 wadcutters only during qualification a few times a year to training with the round you would actually carry on duty. We added actual training to the shoots instead of just shooting for score. Night shooting and shoot, don't shoot training evolved around that time.

That horrible crime resulted in life saving changes to LE training that carries over to today.
