On this week's look ahead: tensions between police, the mayor, and protesters in the aftermath of the shooting of two NYPD officers. Mayor de Blasio and other city officials head to Albany for tin cup day (also known as a legislative budget hearing). A New Jersey panel tasked with investigating a culture of misogyny in Trenton holds its first public hearing. And: this Friday is Valentine's Day — and the deadline to change your party affiliation if you want to vote in New York's upcoming presidential primary.
