How long to you have to lie to police before you're committing a crime?
I think it starts with the lie.
Fine, charge her with lying for those 4 hours, and lets see how much more it costs taxpayers to pursue that than it did to have her sit in their substation questioning her.
Get your priorities straight.
The waste of police resources happened before her lie, when the police decided to search for her before a specified period of time had passed. At that point, she had not lied to anyone, she was acting as a free person, going on a trip.
