For the first time in United States history, a former president may be indicted for a crime.

News 12 Long Island has learned the NYPD has already started setting up security cameras and barricades to prepare for protests if former President Donald Trump potentially turns himself in to the Manhattan District Attorney.

Meanwhile, Long Islanders are reacting to the latest developments in the case.

Some residents in Merrick tell News 12 enough is enough and the case seems more political than anything else.

One resident says, “I think it’s ridiculous, I think that the playing field is not even, and what goes for one should for the other, and to me it sees like a political witch hunt.”

Another resident tells News 12 “I’m OK with it, you break the law you get arrested.”

News 12 checked in with police for how they are preparing if the former president is arrested.

Nassau Commissioner of Police Patrick Ryder said in a statement: "The Nassau County Police Department has had daily intelligence briefings on the matter. If there is a location of concern, it will be addressed immediately with the proper resources as we are always prepared."

In Suffolk, they tell News 12 they have not heard of any protests or rallies planned, but they are remaining vigilant.
