Here's a video caught by a security camera on a front porch a few weeks ago. The FedEx guy is stealing a package that was left on the porch by someone else.
Notice how he pretends to be trying to deliver the package by leaving a tag. Then he comes back and takes the tag.
The guy who owns the house (and the package) happens to be a member here. He tells me that FedEx driver is now unemployed.
It looks like the proliferation of home security cameras is going to be bad news for errant delivery people.
