I agree. She lied. But the same way police interrogators are legally allowed to lie to their suspects, I fear the court will find that she is perfectly allowed to lie in order to trick them into letting her into their home.
That's with probable cause. As opposed to gornischt. The problem here is that there was no legitimate purpose for disturbing these people and throwing around threats. For that reason, I think they're on solid ground.
It's a different situation from being a lawbreaker and letting a cop in, who then sees your bong, a severed head, and $15,000 in cash on the couch.
