Cameron Lee Kirsch on Tuesday posted a letter from Denton County Sheriff Tracy Murphree pretty much instructing his deputies to do the exact opposite of what was done in Parkland, Fla., or “inform your supervisor and we will work to get you re-assigned.”

“All commissioned deputies if you respond to an active shooter you are expected to take immediate action. 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,” writes Sheriff Murphree.
