So basically you're going to court with your witness to tell them you did in fact rear end a guy? What's the point? Telling them that you tried to swerve doesn't make any sense.
Did you get charged with careless driving? It was still your fault you hit him, it wasn't because he stopped when he chose to.
The guy stopped and you didn't/couldn't which means one of two things... you were going too fast or following too close in order to stop regardless where the guy in front of you decided to stop.
If the guy in front of you was able to stop for a yellow in the middle of the intersection you shouldn't have even bothered to try to go through in the first place and stopped for the light and the accident would have been avoided altogether.
