You can’t have unarmed folks dealing directly with the guy by themselves. They should be dispatched at the same time though and on scene together. Some unarmed person dealing with some loony with a knife is how it escalated in the first placeWhat do you think mental health professionals who are trained to deal with this do? And like I said, if it's a situation that they can't handle then calling the cops is always an option. shyt, you could even deploy them at the same time with the cops chilling in the background until needed. There are better ways to do this. You have to see that, right?
