I recently got to spend 5 days in jail for something like that. (Expired stickers was my presenting offense. A .22 was what got me locked up.)
I also paid $451 in fines and somehow got thoroughly beat-up in the process. My memory of the few days surrounding that is not real clear. I had hallucinations.
That was about a month ago, and my ribs are only now healing.
And "they" aren't done with me.

If the DUI, the expired stickers, and the gun offense are all one and the same, you had better start reforming ASAP, Harry.
I'm against any violence not prescribed by a judge ("canings," for example, would be fine by me) in jail, so I feel for your additional punishment to date if you didn't do something from which they were defending themselves. But you are in no position to give your judge a piece of your mind.
Please sincerely apologize and be repentant. You may spend less time in a place you'd rather not be.
