If you plead not guilty, I guarentee (sp, cause it just looks wrong!) you that the cop is going to show up. And I'll tell you that it'll be like a 98% chance that the judge rules in favor of the cop. If you make up a story, then you could also get into even more trouble cause I think that is contempt so then the judge can throw you in jail right then and there. If anything, the people that weren't drinking should have said, "Take me for a breathalizer" cause at least then you could have used that in your favor. I actually would opt for blood test over a breathalizer cause by the time you get taken to a hospital, they admit you to draw the blood and the results come back, it would be less than the breathalizer. (just some input for those who drink, get a blood test! NO BREATHALIZER!!!)
I'd say you really can't do anything though. Pay the fine, take the suspension. You could try looking into the local laws and everything and seeing if you can get out of it cause if the cop said you "smelled like beer" but didn't take you for a breathalizer/blood test, then it could possibly get thrown out. The only one that seems to be like not a chance in hel! to get out of it is the girl.
