If anything, I wouldn't worry about this given the article. The majority of the incidents shown are homeless people berating retail staff over welfare card issues; technically they would be charged with trespassing because the police have to be called to make them leave the store. The example given was a mentally ill woman who had issues buying food with her debit card. If anything, it looks more like a crew of people handling nuisances committed by "regulars" as they pop up. The danger is probably they DON'T commit as much as they could, and put out fires rather than secure help. That is, they just keep enabling the nuisance calls. I'd be worried too about overreliance on this. If the guy suddenly pulls a gun or a knife on what was just being a public nuisance, you are having more or less medical workers in danger of their lives.
