To add to your comments Grizz.
> Most schools have a ink pack attached to the fire alarm to discourage students pulling one as a
prank.
> I too have never seen a 5.56 give off enough smoke to trigger anything BUT that does not rule
out concussion from the rifle being fired.
> Did the shooter have gunpowder residue on his hands and cloths? As a matter of course I am
sure he and his cloths were tested.
Even IF he showed positive for two of the above comments, it does not rule out multiple shooters. Heck we know how efficient and professional the Broward County Sheriffs Department was in this drama.
This shooting brings us to also look at the Vegas shooting back in October. There are WAY to many unanswered variables there. I and others, really believe we heard belt fired weapons being used at the same time single shots were being fired.
In closing, I truly believe that we will never know the truth of either drama. WE the Citizenry are just too fragile to hear the truth.
With that written may I re-suggest that you take a look at Matt Bracken's short story,
Professor Raoul X.
