What can be done if I was charged with simple assault and this was my first offense?

I was pulling into my condominium complex and there was this contractor backing up extremely fast so I honked my horn to make him aware that I was behind him. I went around him and then got out to check my mail. The 2 contractors got out of there truck walked over towards me and got extremely violent. Then the 2 other contractors came over and now there was four of them and one of me. One of my neighbors came outside to try and help simmer things down. Eventually, I was slapped across the face by the main aggressor. I told the other resident to go inside and call the police. Once the police arrived, everything calmed down and police start taking statements from the contractors. Finally, the police came over and talked to me. They told me that the contractors were accusing me of threatening to shoot them. I told them that was false accusations and I wouldn't give a statement without and attorney present. I told them to search my car and condo, I don't own a gun and never have owned one. The police were mishandling the case from the beginning and come to find out it's because the main aggressor's happens to be the son of the police chief. I really didn't want to press charges unless the other guy did because I have too much going on with starting college and just wanted to ignore this because I simply don't have the time. Well, I found out that the other guy pressed charges on me so I wanted to do the same to him but the police already sent the case over to the state. Is there any way I can still press charges? I found out three days later that I was charged for simple assault what should I be expecting and how should I pursue this? Supposedly, they only got statements from the contractors which of course are going to stick together. I find out this guy has previous encounters with road rage in the past. There was a video taken from someone but they won't let me see the police report to see how long the video was or what it contained.
