Private security has been around for what... hundreds, thousands of years?

It hasn't devolved into pulling up in an armored van and exiting with weapons drawn yet. Why would yet another company among thousands (millions?) entering the field change that?

Security forces are professionals, and professionals at dealing with such situations. They'd be very bad at their job if they armed intervened in non-violent or non-pressing crimes. It is like expecting your Uber driver to take a short-cut over a pedestrian lane: maybe they arrive a tiny bit earlier to the one that paid them, but now they lose their license.

If I do imagine this would happen, assume it would be true, then just to be clear: I do not agree with armed interventions to shut down these illegal lemonade stands, and I wished the marketing in the leaked e-mails would have made it clear, that armed interventions of all crime, is what this service is meant for.
