Now you've created bugs where you overturn "not guilty" verdicts, expunge verdicts of cases that tangentially involved cannabis, and fail to expunge verdicts of cases where cannabis wasn't in the text but that still fell under the law change.

Haha if it's not correct to start with it must be some sort of "machine learning".

Besides, how many innocent verdicts for these crimes can there be? Prosecutors don't care near as much about pot possession as cops do (because they're not the ones getting the federal money), and they plea out possession when there's any doubt about convicting on more serious charges.
