There are multiple types of agreements that local and county law enforcement agencies can enter into with ICE, Long explained. Detention center contracts are slightly different from 287(g) agreements, which deputize local officers to assist with immigration detention. These agreements classify county facilities by how long they can hold ICE detainees, Long noted. It is nearly impossible to figure out how many county facilities are designated as short-term detention centers, as they are not made public. Some states, like Florida, have hundreds of these public agreements at the state, county, local, and even university police level.
