New York divorce lawyer extraordinaire Raoul Felder, who handled the celebrity splits of everybody from Rudy Giuliani to Christie Brinkley, kept a pistol in the desk drawer of his Manhattan office for many years.

His reasoning was simple: “Everybody hates divorce lawyers, sometimes even their own clients,” he said.

That animosity was on display earlier this week when police said an Arizona man — upset over his divorce nearly a decade earlier — went on a killing spree that left seven people dead, including himself.

Dwight Lamon Jones did not kill his ex-wife’s lawyer Elizabeth Feldman, but police said he took the lives of two paralegals who worked for her and a prominent forensic psychiatrist who had also worked for Feldman.

“What happened in Arizona was crazy, but not surprising,” said Felder.
