Donald Trump attended Thursday's wake of a New York City police officer gunned down in the line of duty, as the presumptive Republican presidential nominee has made crime a focus of his third White House campaign and accused President Joe Biden of lacking toughness. The visitation for Officer Jonathan Diller, who was fatally shot during a traffic stop on Monday, was being held in suburban Massapequa. Police said the 31-year-old Diller was shot below his bulletproof vest while approaching an illegally parked car in Queens. Diller, who was married and had a 1-year-old son, was rushed to a hospital, where he died. The former president said after visiting the family calling the death "such a sad, sad event, such a horrible thing. And it's happening all too often." "We have to do a lot of things differently because this is not working. This is happening too often," Trump told reporters. Trump's visit comes as Biden was also in New York for a previously scheduled fundraiser with Democratic ex-presidents Bill Clinton and Barack Obama. Trump's campaign made social media posts contrasting his visit with Biden's fundraiser.
