Misuse of The Law™ for what amounts to political prosecution of Trump may cause him some financial harm, and may prevent another successful run at the presidency, which is obviously the main target. However, I think the greater and far more vital damage is to The Law™ itself.
Failure to criminally prosecute violent ‘protestors’ (when they cross the line from legitimate political protest into arson and other damaging assault on persons and property), followed by flagrant prosecutorial rights violations of the J6 protestors and observers, followed by these concerted and tenuous attempts to hamstring Trump in multiple jurisdictions simultaneously, combined with failure to prosecute (or even adequately investigate) crimes associated with C-19 and vaxx abuses, combined with abdication of enforcement of the most basic tenets of civil and society (such as the ability to operate retail sales establishments with goods displayed for easy access) will result in further degradation of whatever civil society is left.
Vigilantism is already on the rise; it’s not a thing that I want to see as the likely ‘pendulum shift’ as people feel directly threatened by rising (and unchecked) ‘actual crime’.
