Never accept any offer at arraignment.
Prosecutors read the citation that the cop filled out in the radio car when the cop cited and arrested you. That is as much as the prosecutor knows about the case at arraignment. The prosecutor has not looked at the evidence at that point, with rare exception.
Don’t make a plea deal with the prosecutor at arraignment because the prosecutor is spitballing. The prosecutor hasn’t seen the evidence, and the prosecutor is taking the cop’s word for it. The cop is 100% of the time going to be bias against you and your interest. It is the cops job to call whatever you did a crime, and it is the prosecutor’s job to make the cop’s assertions stick.
Pleading at arraignment hands over all your bargaining chips before you’ve even started. Unless what you are charged with is a traffic violation or otherwise is a low level offense and the punishment is only a fine or conditionally discharged time held over your held or a suspended sentence or slap on the wrist, do not plead at arraignment. And for the love of all that is Holy, do not ever, EVER plead to an active jail sentence at arraignment under any circumstances.
