The Mourning of Anna Nicole

The sudden death of Anna Nicole Smith still has the city reeling in shock. You can't walk a block without coming across a makeshift memorial. The local supermarkets are even having sales on jugs of milk as a tribute. And then there's the folks over in this Park Slope building in apartment #2 who have taken it the next level; barricading themselves inside for a mourning period while publicly hoping that her memory may be a blessing.
The question is- is the sign an invitation to come in and join them or a warning to keep out?
