Making a false police report in order to send police to someone's home is obviously wrong and should be easy to condemn.
Even this post you appear to be saying there's more to it than that. If you think she's lying you should gather evidence and post it rather than insinuating it.
EDIT: I mean, unless you called the police station to check the details you can either believe her version of events or believe someone else's version. I'm not sure why you'd go for that other person's version without very good evidence.
