An expungement doesn't cleanse the stain. You'd need a pardon to do that. Pardons aren't doled out to common folks. Pardons are for billionaires.

An expungement tries to hide the stain, cover the stench.

It may work in some situations, it may not in others.

Don't mislead yourself.

Anyway, here's the information on expungements in Florida.

Educate yourself, OP:
