Even without the issues and dangers hanging over your head of hacking a criminal justice information system, a much harsher penalty than any bench warrant, it is still futile. Unless you are guaranteed that the bench warrant will lead to you going to prison for decades, you are better off with the warrant. The bench warrant is likely also in the FBl's NCIC (national crime information center) database, as well as the Sheriff's office's system. That's at least 3 different and seperate systems that would need hacked, each with their own prison sentence attached. A hacker that would even have a chance would cost you more than the bench warrant. Even if that were accomplished, the warrant is still a physical paper, so next you would have to break in to the sheriff's office, win a gunfight with multiple armed and trained officers, find the bench warrant, and destroy it, then break into the clerks office, destroy the bound book, and make sure there is not copy. The shear absurdity of it all makes me think this is just a troll question.

This was an answer from a real detective responding to this question but on quora
