New York’s largest ICE detention camp is blocking book deliveries.

ICE is depraved, and every day they seem to find new ways to lash out. Their incompetence—from out-of-shape squadristi getting embarrassed in Chicago to the poorly written snivelings of racist pencil eraser Stephen Miller—hasn’t hampered their ability to hurt our neighbors and communities. There is no more malignant expression of Don Trump and his hogmen’s greasy contempt than police department washouts cosplaying Zero Dark Thirty in our streets. They would be pathetic if they weren’t so dangerous.

ICE’s latest move is to go after books, and keep them from those they’re detaining. An ICE camp in Buffalo, which is the largest in New York, has banned the shipment of all books into their facility, according to a new report in New York Focus. The Buffalo Federal Detention Facility abruptly stopped accepting book deliveries for detainees in July, a reversal in policy. They have turned back packages containing “an illustrated Spanish-English dictionary, the Spanish translation of ‘A Clash of Kings’ by George R.R. Martin, and ‘The Seven Principles for Making Marriage Work’ by John Gottman and Nan Silver,” among others.

New York Focus spoke to members of the Justice for Migrant Families, who said they have regularly sent books to detainees, but that deliveries began to be rejected in the summer. ICE claims this new policy is due to security concerns, even though books are required to come directly from booksellers and can only be accepted inside detention after a long and convoluted process.

The ACLU of New York delivered a forceful letter to the facility yesterday outlining the potential illegalities and inconsistencies of the ban, and demanding that the ICE facility “take immediate steps to end this practice and comply with both its own procedures and the First Amendment.”

An ICE spokesman told New York Focus that the facility has a legal library, e-readers, and religious texts available, as well as other recreation, but this of course misses the point. Depriving people arbitrarily is a vulgar display of power.
