Amid a surge in shootings and murder this year, Queens leaders Friday called for more cops to bring peace to the borough's troubled Southeast."Right now the police department is down by about 7,000 police officers," state Assemblywoman Barbara Clark (D) said at a press conference Friday. "The precincts we have are understaffed and we need more police presence in our communities."Queens District Attorney Richard Brown endorsed the call for more police to patrol Sutheast Queens -- an area where shootings have increased 22 percent in the last year, three times the rise seen by the city as a whole.
