Here’s why I am not a fan. Pain compliance takes to long. If you’re out on your bike with your wife and someone tries to do something stupid…you’re at a disadvantage. They are either armed, or in an altered state, or they have lots of experience doing what they’re doing. You might get one or two strikes before shit gets really intense. A motivated person is going to shake it off and keep coming at you. I have experienced this firsthand. I had a shield and armor as well as a big Fuckin stick with a rib separator. Enough pain anyone becomes compliant. Question is lasting long enough to get them there.
