I THOUGHT THIS IS WHAT EVERYONE TRAINED FOR, POST-COLUMBINE: Denton County Sheriff: We don’t wait, we engage active shooters.

“We do not stage and wait for SWAT, we do not take cover in a parking lot, and we do not wait for another agency. We go in and do our duty. We go in to engage and stop the shooter and save lives,” Sheriff Tracy Murphree wrote.

Murphree said the memo was designed to make his policy clear on what to do in situations like a school shooting.

“If for any reason you cannot follow this directive please inform your supervisor and we will work to get you re-assigned,” Murphree wrote.

That seems both fair and responsible.
