Replying to So im in an akward situation and i want some real help not bullshit

im 16 years old and like most people in highschool i drink.... well i got caught at a party dirnking the day before thanksgiving and i got underage consumption and possesion.. i now have court feb 1st and this past saturday i thoguht i would be safe dirnking again we had a dd and i was at a house it wasnt too crazy.. but at the house someone stole 1200 from the guy who lives there and now supposivly eveyrone who is there is getting questioned and possibly getting a lie detector test... im sure there mostly concerned about the money but if the cops didnt actually catch us with beer or dirnking only through a lie detector could that be used in court against me on feb 1st or since everyone was drinking do you think they will care and are just more worried about the money... i think a detective is coming to eveyrones house to question them so i just dont want to have to say i was dirnking and them see that i have court for it then get screwed....
