"The FBI traced the threat to a out-of-state source and determined it was not credible."

Why won't they say who made threats to the school?   Were they juveniles, and this is the reason their names weren't given?  If they were adults, why can't they release the names?  Threats to schools should be taken seriously.  Didn't they evacuate the school?  The threat was serious enough to evacuate the school, but it was not "credible".   The FBI traced the threat to an "out-of-state source" and determined it was not credible, but they won't say who did it.    

I wouldn't be surprised if a crazy trans didn't do it themselves just to discredit people complaining about the violent transgender boy.  Trans, Antifa, trantifa and their overly zealous followers will do anything.  Public sentiment was going against them, so they will do anything to discredit their opponents and make them and the school look like victims.  

Remember the men dressed as Nazis that slipped into the KJK Let Women Speak event in Australia.  They were planted to discredit KJK. 
Liberal MP Deeming said the police let them through the buffer zone.

When things aren't going your way, just create a huge distraction.  Representative Jamaal Bowman, D-NY was caught pulling a fire alarm at the Capitol to delay a key vote.   There was no fire.  

All this is weird shit.  Parents need to be very careful, and make sure that everyone knows that they don't condone violence.  Be organized, disciplined, and non-violent.   Look out for suspicious infiltrators.  Any group tarred as far right by the Biden administration (whether they are far right or not) can be infiltrated (undercover FBI agents at January 6 egging protesters on).
