Since you aren't a lawyer let me
throw out a few facts.
Charges were never brought wrt PACER, thus nothing to "drop".
American justice punishes you at sentencing if you decide to exercise your constitutional right to trial. Last time I dealt with it you got an extra six points added at the federal sentence level.
Aaron had legitimate access to JSTOR. If you read the indictment that's why they claim CFAA wrt him violating contract by using a scraper program. BTW most legal scholars decry the facts in this case. And the victim JSTOR along with local law enforcement weren't even going for one felony, much less going from four to thirteen in an effort to intimidate the defendant into a plea agreement to further their careers. That is what happened here, not a "pursuit of justice".
Aaron not only thought they were in error (he would not plea), everybody but Carmen Ortiz's office considered the DOJ actions egregious.
