I doubt it would be “contrary to public interest” for the public to know more details about this crime. Such as, who else is involved, where did the killer get tear gas, and who financed everything?
Especially the families of the victims.
It would certainly be contrary to public interest for the other suspects to have any clue about the investigation.
Addendum to my 14: “...which their enablers in the media and government would only too quickly supply them with.”
It’s in the public interest to let law enforcement do its job and lock this perp up permanently. It’s not in the public interest to turn it into a circus like the O.J. trial or the Zimmerman case.
The public and the family will know all there is to know in due time. We want this done right, and our curiousity simply does not count.
He didn’t have tear gas. It was smoke grenades.
“where did the killer get tear gas”
Well, he was a medical student, so there’s a possibility that he could have concocted the stuff himself.
