Despite Mayor de Blasio's recently announced homelessness initiatives, some advocates are blasting the city for an approach they say continues to criminalize the homeless.

At a rally Monday, the New York Civil Liberties Union announced it is prepared to file suit on behalf of three homeless New Yorkers whose belongings were destroyed during a raid on an East Harlem encampment.

During the raid on October 2, captured on surveillance video, city workers in protective suits can be seen loading material into a dump truck. Those targeted say birth certificates, social security cards and medications were destroyed.

"I believe my rights was totally violated, by them taking my property and throwing it away in a dumpster, like I'm nobody, like I'm nothing. I am somebody. I am something,” said Floyd Parks, who filed a notice of claim against the city.

“Obviously, homelessness is a much more high-profile issue than it has been in a long time this year,” said Alexis Karteron of New York Civil Liberties Union. “And we think that's why this happened, because the mayor, the police department, are under pressure to address homelessness. But at least on that day, they went about it in the wrong way."

Noting the incident took place at a school, City Hall released a statement saying, "It is illegal for individuals to trespass and sleep on school grounds, and we will not tolerate it."
