First, I like this model of private policing. In the instance the article sites, the security force went at the heart of the problem rather than throwing someone into a cage. That’s a good thing.

Second, if you have a failure from a public institution, a private alternative is a good thing. You get more competition, which often yields better results.

Third, this isn’t very thought out, but trimming public police forces and dedicating funding and staff to more serious types of crime while allowing private police to handle petty crime could be an interesting use of resources.
