Ahh, but if they all arise at the same time the “bad” guys will be way outnumbered.
I think this tactic is used in cities and school districts here in the United States.
Enemies of the mayor-city council and school superintendent-school board are identified and discredited.
No one gets arrested for opposition but codes enforcement is used by cities and infiltration of groups that oppose the status quo do happen.
This helps to confuse the opposition and discredits their position with the public.
In one Democrat controlled city some years ago (York,PA) there was a simultaneous roundup of Republican leaders in the city for unpaid parking tickets.
