On February 15, 2018 the ACLU urged the Senate to vote NO on Amendment 1948 (Stop Dangerous Sanctuary Cities Act).The Stop Dangerous Sanctuary Cities Act perpetuates unconstitutional immigration detainer practices, and upends hundreds of community trust policies. Rather than taking a punitive approach to local law enforcement agencies that are working hard to balance their duties to uphold the Constitution and to keep their communities safe, the Senate should end DHS’s unconstitutional detainer practices, or fix the constitutional deficiencies by requiring judicial warrants for all detainer requests.
