I'd go with everyone being told not to discuss it because there is going to be a coroners investigation. Thats the same as a 911 commission. Who's our favourite coroner? will they ship him in for this one?
Refering back to the Truth hertz program, unverified claim, there were 6 eyewitnesses to Columnbine who testified multiple shooters, not 2, multiple. Claim is, testimony not heard. All 6 are dead. It was over a decade ago. I don't know who the witnesses were or their age. It's possible they fell of the perch, but if they weren't that old, it would be a stretch for 6. IF 27 is easy peasy in this environment, more is not going to be a big deal.
