In reality, he would have retreated while shouting "Eff you, mothereffer", while dialing 911 to inform the police that a knife-wielding ch!nk tried to mug him. And the guy would have spent tens of thousands of dollars defending himself in court, since in NYC, carrying a knife with more than a 2-inch blade is illegal. An NYC acquaintance (who's now deceased from the usual old age maladies) once pulled a gun on a knife-wielding mugger, who reported him to the cops. Net result was he spent the night in jail and incurred tens of thousands in legal expenses staying out of prison.
How much would multiple leg fractures, etc. cost him in the hospital?
That’s the thing about gun tyranny places. Since citizens aren’t supposed to be armed, criminals can run roughshod.
Would $10k be worth not getting killed by such thugs?
