The Guardian Angels founder Curtis Sliwa was being interviewed live from Times Square on Tuesday night by the Fox News host Sean Hannity when their exchange took a startling turn.

The topic was what both men seemed to agree was a migrant-fueled wave of crime and chaos that they claimed had overtaken New York amid a surge of arrivals into the city from the southern border over the past two years.

Suddenly, Mr. Sliwa had a prime-time example. As he spoke, the half-dozen red-jacketed Angels flanking him slipped out of the frame.

“Our guys have just taken down one of the migrant guys right here on the corner of 42nd and Seventh where all this is taking place,” Mr. Sliwa said, pointing off camera.

“Can you pan the camera?” Mr. Hannity asked his cameraman.

The cameraman swung around and captured the Angels confronting a slightly built man in a hooded sweatshirt, throwing him to the ground and putting him in a headlock.

“He is out of control,” Mr. Sliwa said as the camera turned away and Mr. Hannity shifted to criticizing President Biden over his administration’s border policies.
