Violence and crime is going to happen. This doesn't mean we ignore it, but it is a tough balance because you can't go overboard either.
It's a difficult decision when people can die. I'm not going to pretend that it isn't. It's always going to be arbitrary and people are always going to disagree on how safe we need to be. But the fact is that nothing is ever totally safe. It's always going to be a tradeoff for something else.
Accept, but don't neglect. Even an impregnable fortress needs a sally port.
