What she did or did not do, what her family saw, or did not hear, what the police did or did not say is immaterial.
The police department secured a search warrant based on THE TRASH. If I am the only cop that sees this as wrong as hell, then I am sorry. I am not about to dig through someone's trash to get into their house. If they are not doing anything other than that, they arent that big of a fish to fry, in my opinion.
Real bad guys do stuff to other people, outside of their homes.
