My POA has tried to fool with enforcing certain association by-laws and has gotten ignored or slapped down. Sheriffs most don't care what happens on private property unless it reaches felony status. The county doesn't take sides if anyone from the POA stands up against a POA decision; they ask for the POA to sort it out amongst themselves. The board has gradually come to realize that the owners are not going to tolerate partial enforcement and full enforcement is impossible, therefore there is no enforcement (of controversial covenants).
Last place to go to on a covenant violation is the cops ~ you really need to go to court first ~ after consulting with the miscreant.
The pigeon guy actually went to the cops about neighbors killing his birds ~ which is how we found out about the flock.
