Three of my friends and I are college students in PA. This past weekend we were having a party at our house and unfortunately the police came. One underage person who was there attempted to run but was apprehended and will be charged with MIP. The policeman had us instruct everyone else to leave and lectured us fairly hard.
After it seemed that everyone had left, he told us to check and make sure everyone was gone. When we came back out, we found out that 2 more underage persons had come out from the front door. We believe that the police attempted to breathalyze them, however the machine failed and they simply drove them back to their room. We do not know if they will be charged.
So, my friends and I are now being charged with providing alcohol to minors. It seems to us however, that since the police never entered the house to find evidence of the alcohol we allegedly provided, we should have a strong defense in court. Are we correct in thinking that this charge should be avoidable?
