The have been many stings all over the country that featured AMPs that were closed by LE and then re-opened "under new management". LE looks to capitalize on the fact that not everyone was aware the place was closed down. I think there were links to articles about this posted here at UG.
I have seen AMPs change names, change owners, close temporarily (no LE notice on door) then re-open. Maybe other mongers know differently, but I have never seen an AMP closed by LE that then re-opened later. What AMP owner would want to pick a location that was targeted by LE?
