Why wouldn’t they? It’s an efficient design, and aside from the whole force thing they seem to be working with the same physics that we are. Why wouldn’t they invent philips head screws?

Once I called them because two guys were beating up a homeless guy. they never showed. They called three hours later and asked if I still needed them to drop by. Their stated policy says that they will show up within 15 minutes if people are in danger. I guess homeless people aren’t people.
