Do not do this at home: FB post leads to burglary
A teenager in Australia posted a photo of a big stack of cash (her grandmother's savings) on Facebook. Hours later, two masked and armed men forced their way into the house to get to steal it. They didn't find the entire amount and left with just a small amount of money.
Moral of this story: Do not post photos of valuables, or the fact that you're leaving the house unattended, on social media sites.
