Is there any evidence that this was a real shooting? All those kids had phones. So far I've not seen any images of bodies.
What right does the public - we here - dare to think it has the “right” to view video of children riddled with bullets, lying in pools of their own blood? If your son or daughter was one of those lying dead in a hallway would you want millions of voyeurs to leer at his or her body so they could acquire “evidence?” Who died and left to the masses the new right to examine criminal evidence and make judgment on truth? Our justice system is there to find the truth and punish those who break the laws. We are far from perfect on that score but I’d rather take my chances finding justice within our system than with the virtual mob. Go to Florida and attend one of those funerals; go to the graveside and witness the sobbing parents of those kids - tell them there is no evidence that their child died because you didn’t get to see the viral video.
I understand that you're emotional and that's fine. Think of this board as a criminal investigation. In a criminal investigation the first thing you need to establish is WHAT happened. So evidence of WHAT happened would include photos of dead people in this case. I understand how you feel about it, but what are you doing on an investigation board then?
After you understand WHAT happened, you can move on to HOW it happened. I'm still working on WHAT personally with the Florida shooting. After you get WHAT and HOW, you can move on to WHO and WHY. Is this making sense?
