Saw on T.V. where a couple allowed their daughter to have a party in the basement and invite her friends. The parents were very careful no alcohol, drugs, etc and watched as the friends arrived.
Later that night poice showed up on a noise compliant or too many cars in front of house or something like that. the parents answered the door, police asked if they could search, they said yes and police barged right past them. Police found alcohol and drugs, underage kids downstars. Turns out daughter had let more kids in the basement door who had drugs and booze
Parents prosecuted, over $100,000 in legal fees so far.
A real nightmare. The parents said they didn’t have to consent to search and the premise of the show (20/20 I think) was that you NEVER benefit by allowing a search.
