At first glance, Matthew Ortiz's lawsuit makes sense: He was shot in the leg at an Italian street festival in Ridgewood back in 2008, and wants the NYPD to pay up. But the thing is, the police didn't shoot Ortiz; he caught a bullet from random gunfire in the crowd. Nevertheless, his lawyer says the cops, not the perps, are to blame. "There were a number of mini-riots, and the police presence was practically nonexistent," attorney David Harrison tells the Post. "If stuff going on gets worse and worse... it's negligence. " If Ortiz cashes in, expect future lawsuits against the NYPD for failing to save New Yorkers from such dangers as flying pillows.
