im in Arizona and I was at a football game. I had a couple beers before but I wasn't stumbling drunk. I went to the bathroom and got asked by these cops dressed as fans to take a breathalyzer test. I didnt know what to do so I took the test and got a .06. They gave me a ticket to appear in court but I heard that portable breathalyzers aren't substantial evidence In court. I also did not tell the cops I was drinking. Do I say I'm guilty or can I fight it saying I was given a spiked drink at the game or something
