Agreed, but they need iron clad cases. Worst thing that can happen is to put any one of them on trial, only to have them skate on a technicality.
That said, they will stage another shooting or event to change the narrative. This school shooting coverage has jumped the shark, and only incentivizes the next nut job who wants their 15 minutes (or 7 days) of fame, dead or alive. How many shootings were there 15 years ago? How many now? The media has created a lot of this, in my opinion, all for the sake of ratings, and one of the Parkland parents said something similar in an interview.
