Death threats. Soliciting without a license. Panhandling without a license. Illegally parking in a business. You name it the cops got something they can get this kook with.
I have to deal with a dozen or so panhandlers everywhere I go, even if I'm just going to buy groceries. I doubt very much that any of them has a license. I've never even heard of a panhandler's license. With my very limited understanding of law, I'm pretty sure 'soliciting' is a different thing. But, I'm not sure of the details of all this.
The death threat was not really serious. It's more like my boss telling me, 'If you lose this account, I'll kill you!'. I don't think I could have him arrested for that.
