NYC millionaire faces three years in jail for using unlicensed gun on a burglar inside his home

Why should people need to go through a costly and time consuming procedure to have a gun in their home?  In any case, this was a gun that was legally registered to the man's bodyguard.  So what exactly is the problem?  Can't you pick up a gun that is available when you need it if it is legally registered to another person?  This citizen even was the person who called the police!

A Manhattan millionaire faces three years in jail for drawing an unlicensed gun on a burglar inside his home . . .
Mr. Bardwil, 60, threatened the intruder . . .  The man fled and Mr. Bardwil called the police.
After showing the cops footage from his home surveillance cameras, they arrested him under suspicions of owning an illegal firearm.
The businessman’s lawyer, Michael Bachner, told the New York Post that the gun is legally registered to the defendant’s bodyguard.
“There’s no dispute that George was being burglarized,” Mr. Bachner said. “George had been the victim of multiple burglaries, and the DA’s office concedes that it was used in self defense.” . . .
