Waste not, want not. Of course someplace that sits vacant for years is going to attract someone eventually. In an economy where folks are losing everything through no fault of their own, driven to it by greedy corporate raiders and sleazy bankers, it makes sense that this sort of thing would happen. People will do what they have to survive.

And those who advocate committing murder as a response should do us all a favor and point the gun at themselves to gracefully eliminate one more sociopath from the gene pool.
