Hays:Is not having an audio of the incident enough to ask for a minor in possession ticket to be dismissed?

Hays Kansas: My 18 year old daughter (driving with 4 friends), pulled up in front of a house in Hays (8:00 pm the day of October Fest). Her car was surrounded by 5 policemen who shinned flashlights in the vehicle. One of the passengers in the back seat had alcohol on her lap. All were ticketed for minor in possession. I've requested audio of the stop to see if there was a reason, we were notified last week that they have no audio. My daughter said she did nothing wrong to be surrounded, they overwhelmed her, scared her, and weren't very nice to her. I was told that it is mandatory for police to audio record every stop. Is there anything I can do to help her?
