can you prove abuse?
Easily.
Who IS Fani Willis anyway? She is a radical Marxist who is part of the Soros cartel. The Open Society Foundation funded law school for Willis. Then the Soros gang funded her run for DA as part of the Soros plan to destroy American Jurisprudence. A plan, a conspiracy really - which has been highly successful and has left the once most respected legal system in the world and smoldering heap.
Willis campaigned on the promise that she would "put Donald Trump in prison." This alone is prosecutorial misconduct. No investigation had been done, and the Soros cartel announced intent to corrupt and pervert the law to imprison their political enemy.
Beyond this, of the 41 counts Soros lodged against the last legitimate president, 11 of them are unquestionably federal - Willis is committing a federal misdemeanor by illegally usurping federal authority. Merrick Himmler is just as corrupt as Willis, and in collusion with the Soros Cartel to attack the political opponent of the democrat Reich. As such, he will not charge Willis - the law does not apply to democrats.
