Since this is a false claim and it has been even filed with the police while targetting Michael, MJ's team needs to be pro-active. Otherwise, if they just let it go, people will feel they can take chances to see if their fabrications against him become successful, and it give professional fraudsters ideas to become more creative in targetting his vehicle.
MJ's team needs to also file a formal request to the police asking them to take action against the man who filed the false claim. And they can even launch a lawsuit against him as it constitutes attempted fraud. This may appear a waste of time and money, but a stitch in time saves nine.
We saw with the Arvizos, it began with Bashir, the Arvizos copied the lie to take advantage, then Kapone copied Arvizos, then Bartucci, each trying to see how far they could get with their false claims.
But if MJ takes action, atleast asking police to take action, then people will think twice before they try these scams.
However, if his team slack as they usually do and let this pass, some other guy will borrow this guy's idea and try to make up something else, even deliberately knocking MJ's car with cameras absent, then filing a multi-million lawsuit.
And the police have a responsibility to do so, just as someone commented on this site
