Just a quick tip, dont listen to people about the cops most likely not showing up. If thats your only means of defense then your fucked. What most people dont realize is that Cops DO in fact get paid to show up in court and fight against you. So unless your cop gets killed/kidnapped on the way to the courthouse chances are thats not gonna work. Im not saying it doesnt happen but its not something id ever rely on.
Id say stick to your guns and just try to fight it. Best case scenario it gets dropped and nothing goes on your record, But if worst comes to worst your in the same boat your in now and you just gotta pay out some cashh.
