Nationwide, at least 14 police officers have been killed in the line of duty this month — and many more have survived gunshots.
But that doesn't mean there's a "war" between police and criminals, says Sgt. Norman Jahn, a 20-year veteran of the Las Vegas Police Department.
"The approach we have to take cannot be like the military," Jahn tells NPR's Steve Inskeep.
"We are civilian police," he says, noting that the situation in Las Vegas and other U.S. cities is far from what it is in parts of Mexico or Afghanistan.
