What can I do about my disorderly conduct while an immigrant?

I am a natural citizen of the United States. This past March 2012 an incident happened that might change my life forever and for the worse!! Me and my husband decided to go out and have some fun. So we went to a Mexican concert where we danced, laughed, and drank since we weren't driving. On our way out after the concert I noticed that the sheriffs we're body slamming a woman, so I approached the incident and like I was holding a camera I guess the sheriffs thought I was recording the incident and they felt threatened so they approached me very aggressively and immediately handcuffed me b/c I was very disturbed with the whole situation. Meanwhile my husband was right beside me when one of the 6 or 7 sheriffs that were there grabbed a can of beer that my husband was carrying in his shirt pocket (unopened) while that made my husband furious b/c the officer ripped his shirt. Immediately they handcuffed my husband and threw him on the ground hurting his knee, shoulder, and face b/c my husband couldn't put his hands in front of him b/c he was handcuffed. Well they didn't arrest us that night but gave us court dates and we were charged with disorderly conduct. Today April 16, 2012 we had court it turned out we couldn't plea guilty b/c the victims weren't there so I asked the Judge.."AREN'T WE THE VICTIMS??" she said "NO!" anyways now my husband has another court date, has to pay a fine of $800.00 and what scares me the most is that they said he might also face time in jail then DEPORTATION!!! LIZ my husband has NEVER been in any kind of trouble whatsoever with the law nor has he ever been in jail before. This was all my fault b/c I thought the sheriffs were violating that woman's rights. I petitioned my husband's papers 5 yrs ago and this can't be happening there's got to be something I can do to stop this. I son't know exactly what the outcome will be of the next court date hopefully they just ask for the money and that
