Never been to FL and probably never will
But I can't blame the fans for loving Michael so much. It's all because of the outpouring of love coming from their hearts.
Vandalizing the tomb is completely unacceptable, but FL administration should expect it--they knew they would deal with huge crowds for a dead celebrity.
They should have some standard policy to handle the situation. A plan should be worked out with the family somehow to keep security next to Michael's tomb on a 24/7, at least during mark dates.
