State and federal authorities are closely tracking online criticism and protests against the immigration crackdown in New Orleans, monitoring message boards around the clock for threats to agents while compiling regular updates on public “sentiment” surrounding the arrests, according to law enforcement records reviewed by The Associated Press.

The intelligence gathering comes even as officials have released few details about the first arrests made last week as part of “Catahoula Crunch,” prompting calls for greater transparency from local officials who say they’ve been kept in the dark about virtually every aspect of the operation.

“Online opinions still remain mixed, with some supporting the operations while others are against them,” said a briefing circulated early Sunday to law enforcement. Earlier bulletins noted “a combination of groups urging the public to record ICE and Border Patrol” as well as “additional locations where agents can find immigrants.”
