Now that fits the details of the various reports.

I’ll bet the only “active shooter” was the LEO’s.

"I’ll bet the only “active shooter” was the LEO’s."

That seems a good guess, if only a guess. The reported shots were fired in close sequence, then nothing. Other reports are of a car ramming people, and a perp with a knife or machete, and mostly non-life threating injuries. So a likely scenario is a machete-wielding perp gunned down by the cops, with some students detained for precautionary reasons, because they were in the area.
