Despite calls for his resignation, Indianapolis Public Safety Director Frank Straub said he's committed to seeing his department through the trying times following several high-profile embarrassments for police.At Monday night's City-County Council meeting, protesters from the Baptist Ministers Alliance expressed outrage over a string of recent problems inside the Indianapolis Metro Police Department, including a botched investigation of an officer authorities said was driving drunk when he hit a group of motorcyclists, killing one, and recent allegations of police brutality.The group blames Straub for low morale at the department, which some said they think has spurred some officers to bad behavior.But during an interview with 6News' Joanna Massee on Tuesday, Straub defended his position and his performance, citing a 13.5 percent decrease in violent crime in the city. "I think people are in the community, or in some segments of the community, are very hurt," Straub said. "I think Chief (Paul) Ciesielski and I and the command staff have a very good team, and I think that despite what I would call bumps in the road, some bigger than others, I think we can move forward."Mayor Greg Ballard voiced his support for Straub in a statement released Tuesday."Director Frank Straub and his efforts to reform the Public Safety Department and fight crime in our city have my full support," he said.Meanwhile, Democratic mayoral candidate Melina Kennedy said she thinks it's time for Straub to move on."We have to see some leadership. This is too important, and I think changes are in order," she said.But Straub said he's committed to guiding his department through the current challenges."It is my obligation as the director, and whether I leave or don't leave, the next director, I think, has a moral obligation to make sure that we uphold the integrity of this department," he said. "I'm not thinking about leaving. I'm here for the long haul."
