if you’re interested in seeing what private police in the gate looks like do some research about the private security industry in south africa it’s a lot like that, except the police aren’t underfunded and incompetent, they’re non existent. they install alarms, they act as armed first response, guard commercial premises and often even have their own foot patrols in neighbourhoods that can afford it.
All the batkids hate to skip patrol when injured, but Cass is the worst. At one point she breaks her foot (not on patrol, mind you. It was an ill fated attempt at skateboarding) and has to miss a month of crimefighting. It takes a team-effort of the entire family to keep her from going insane with boredom. They're mostly successful at keeping her on the sidelines, although she still somehow manages to take out eleven criminals while on crutches and in civvies.
