You should definitely start by pleading not guilty and requesting a trial with all officers present, and then once you get notice of trial you can request disclosure (notes from all officers present) in order to see their case against you.
As a side note, I was recently at the court house and heard he prosecutor and 2 police discussing a charge of drunk in public with the gentleman charged. He said that he was sleeping in the house next door and was sleep walking when he went over and was banging on the neighbours door. The police were called and laid the charge. During the discussions though, both police officers agreed that he was barefoot and in his pajamas (supporting he was sleeping next door), and that although they charged him with drunk in public they both said that it seemed a little "strange" as in "something was not the same" with their usual calls for drunk in public. The police and the prosecutor all agreed with his explanation that he had been sleep walking and they drop the charge.
