Earlier this year, Police Commissioner James O'Neill admitted that a "theft of services" arrest (the legal code name for turnstile jumping) could in fact lead to an immigrant getting deported. And earlier this month, a series of bills the City Council passed last year encouraging the use of civil summonses instead of arrests for quality of life crimes like public drinking, public urination and littering went into effect.
Excusing criminality in a matter of deference to foreign nationals who are unlawfully present in the United States is perverse. The immigration laws have many provisions by design to ensure that foreign nationals who violate the laws of the United States in certain ways are not allowed to remain and harm the safety of Americans.
