Cooperating with criminals is a bad strategy. (This is usually a white man railing on about robbery. What does the Left tell a woman confronted by a rapist, or a minority confronted by a racist? Does their advice change?)
Anyway in this case, giving the bastard some money didn't guarantee anything.
After the robber got some cash, he shot [the victim] in the left arm and ran off.Self-defense doesn't always work. But doing your best imitation of a sheep led to slaughter won't ensure your safety either.
