And from Columbine to Parkland, these guys have distinguished themselves with extraordinary courage in their fantastic capability to run away and "form a perimeter".
On April 20, 1999, Neil Gardner, an armed sheriff's deputy who had been policing the school for almost two years, was eating lunch when Eric Harris and Dylan Klebold arrived at Columbine with their deadly arsenal and deadlier intentions.
Gardner said he got a call from a custodian that he was needed in the school's back parking lot. A few minutes later, he encountered Harris, and the two exchanged gunfire. The exchange with Harris lasted for an extended period of time, during which Harris' gun jammed.
The deputy and the backup he immediately called for exchanged fire with the shooters a second time and helped begin the evacuation of students, all before SWAT teams arrived, and before Harris and Klebold eventually killed themselves in the library.
He was clearly outgunned, but does that mean he lacked courage?
