The office’s active shooter protocol says that on-scene deputies, without approval from a supervisor, “may” engage the gunman. That appears to give deputies discretion, but only to a point: They “may” choose not to go in if they know a door is armed with a large explosive device, for example, or if they know the only way into a building has a dangerous suspect immediately on the other side ready to shoot the deputy, Col.

Mr. Peterson told the first police officer to arrive, from the Coral Springs Police Department, that he believed the gunman to be outside, Mr. DiRuzzo said. The officer took up a position behind a tree with a rifle about 20 yards away from the deputy.
Mr. DiRuzzo also credited Mr. Peterson with “the presence of mind” to have administrators review surveillance camera footage to try to locate the gunman, and to provide his building keys and a diagram of the campus to specialized Coral Springs and Broward County units when they arrived...
