Is the City of Miami Extorting its citizens?

Here's a worrying story from the Coconut Grove Grapevine. Apparently, Code Enforcement has been sending out fraudulent notices of violations. In the case the Grapevine cites, there were no signs of any violations.

The most disturbing report comes from the Fire Extinguisher service:

They then asked if we were in the City of Miami. I told them yes. They then told me that they have received many, many calls about this from City of Miami residents, and no one who was cited has been in violation.

Perhaps we need to have the FDLE take a look into this. Or 60 Minutes.
