They very clearly do not take orders from an ostensibly racist 70 year old. That's beside the point, because she wasn't giving orders; she was complaining about her neighbours on the internet, not to the cops. Lastly, it would be extremely surprising if she'd done the same thing twice, let alone ten times.

It's clear that she was in the wrong for being bitchy on social media, but how could she have predicted the outcome? In what sane world do the police seek out unfounded accusations on social media then act on them?
