The second incident, which happened less than 6 months later, occurred at a shopping center.
While making his usual rounds, "Bob" noticed a man yelling at the clerk in a cigarette shop. Bob decided to step inside to make sure everything was OK. The guy yelling at the clerk turned around and brandished a box cutter.
Bob was carrying his firearm at this time, but the clerk was right behind this madman. So, Bob drew and readied his asp (baton) instead. This guy was not as bright as the guy in the first story. He charged with the knife held out in front of him!
Bob swung and hit the guy in the hand and wrist, disarming the crazy guy. However, the guy continued his charge, and proceeded to grapple with Bob. Bob and the clerk overpowered the guy, got him cuffed, and had police and EMS respond.
The guy had several broken bones in his hand and wrist. He was on methamphetamine, and apparently didn't even feel the pain. It turns out that he had been recently released earlier that day from the behavioral health center across the street.
