Did a delay in response give the gunman more time? Cops face questions over why it took three hours for SWAT teams to storm Orlando nightclub as police chief admits officers may have shot some of the VICTIMS | 13 June 2016 | Orlando police are facing questions over why it took three hours for a SWAT team to storm the nightclub where ISIS fanatic Omar Mateen slaughtered 49 people. As the largest mass shooting in modern U.S. history began to unfold, an off-duty police officer working at a gay nightclub exchanged gunfire with the suspect. But authorities chose to hold off on letting the tactical units enter Pulse nightclub, where more than 100 people were shot. Police Chief John Mina has also admitted that some of the victims may have been hit by officers' gun fire.
