A Trump Ally Is Training 75 Armed Citizens. Is That a Militia?

The leader of a New York City suburb is recruiting 75 armed citizens, many of them former police officers, for a force of “special deputies” to be activated whenever he chooses.

Nassau County Executive Bruce Blakeman, a Republican who has allied himself with former President Donald J. Trump and thrust himself into the culture wars, posted a call in March for residents with gun permits and an interest in becoming “provisional emergency special deputy sheriffs.”

The posting called the initiative a strategy to assist in the “protection of human life and property during an emergency” such as a hurricane or blackout — and perhaps, Mr. Blakeman later added, “a riot.”

The new force has drawn vocal opposition in this well-to-do Long Island county, which is one of the country’s safest, protected by one of the largest police departments. It has plunged Nassau into a national debate about authoritarianism in an election season that some see as fork in the road for American democracy.

Mr. Blakeman said in an interview that the program was about “providing another layer of protection” for residents. “I didn’t want to be in a situation where we had a major emergency and we needed help and people were not properly vetted or trained,” he said.

But critics have accused him of creating, with little notice or explanation, an unsanctioned militia answering only to him. They called the move especially dangerous amid heightened fears of political violence, and as Mr. Trump promulgates plans for mass deportations and quashing dissent.
