What will the consequences be?

Hi how are you? So im in some trouble. Last weekend my friends parents had left to México so my friend decided to throw a party. She didn't invite a lot of people but i guess word got out on twitter and posted her address. People started showing up and it got out of hand. People ended up bringing liquor and marijuana. As soon as my friend saw the weed she told them to get out because she didn't want that in her house. But some refused to leave. Then someone called the cops and many ran but only 35 got arrested and the others got away. In the station the woman at the front desk was being very disrespectful to us and basically ridiculing us. We offered to take a breathalyzer test three times and the lady at the front desk kept saying no. Also, a friend who was pregnant was also arrested and she really needed to use the bathroom and she asked the lady at the front desk three times and she ignored her till finally she said "sit the fuck down, just because you're pregnant doesn't make you a parent" there was no reason for her ti disrespect her in that way. Two other friends that were sitting were talking and the woman in the front desk again disrespected them by saying "shut the fuck up idiot." The way we were treated was very disrespectful.
