Well, the police are fully engaged...dedicating themselves to stopping violence and helping the neighborhood feel safe again. They suggest that "whatever you do, comply with what the robbers want because whatever you have is not worth being shot over."
If YOU decide that your right to life, property, or your body is worth defending, then you are in direct competition with law enforcement. It's a stacked deck in that you're subject to the whims of that same said law enforcement. When it comes to your life, you are ultimately responsible for it.
