If they can't find any bad guys, they'll get a dozen fbi agents, form a crazed group, entrap some half wit, and send him to prison for 40 years.
They can use the same group they used on Jan 6 in DC.
It’ll be hard for the feds to use the same tactics they did for Jan. 6. The problem for them is that the protestors in these school districts know who has children in the school/s and won’t be easy to infiltrate. They may be able to monitor their internet accounts and try to impersonate a parent in the district but I doubt that that will go over well and they will be outed quickly.
