Authorities down in DC have now indicted a total of 19 people in the May 19 attack on a peaceful protest against Turkish President Recep Tayyip Erdogan — including 15 of Erdogan’s bodyguards.

The goons waded into a crowd of mainly Kurdish- and Armenian-American demonstrators, hospitalizing nine. Sixteen attackers were charged back in June; the three new additions are all Turkish security officials.

Most remain at large back in Turkey. They’ll be hard to bring to justice: Erdogan has plenty of other thugs he can bring along to New York City for next month’s UN General Assembly.

A warning to the sultan’s goons: Don’t try this when you face fresh protests here. The NYPD will be on the job.
