My question involves criminal law for the state of: Missouri. So about 3 months ago me and some college roommates threw a rather large party on homecoming weekend. Eventually cops showed up but we decided not to answer the door as we figured they most likely had no right to just barge into our house. I had been in this situation before and cops had never just barged in, they always just surrounded the house, banging and shining lights on the windows, and eventually left after awhile. Likewise, they sat outside of our house for about 4-5 hours, towed several cars that were illegally parked (we did tell people where to park but several clearly disregarded our warning), and arrested a few people outside for MIP's, Drug Possession, etc. However, me and my roommates received no charges and no letters or any type of warning after this party.
We haven't had a party like this since, but I was wondering what would happen if we did decide to have another party (most likely not as large) for new years? Basically, what will the cops do if they bust our party and we decide to just have everyone stay, wait it out, and not answer the door again? Like I said, it's a college town so more than likely there will be ages varying between 18 and 22. I myself am 20, with only one roommate over 21.
Also, my house is a little ways off campus, and the noise can't be heard from outside since we always throw our parties in the basement. I believe the cops were forced to bust the party last time due to the illegal parking possibly being a safety hazard.
Long story short, what would happen if cops did show up to this second party and we didn't answer the door again?
