Dog poop, GPS trackers and security cameras: Cracking down on Christmas package thieves

Customers are increasingly using Amazon, EBay and other retailers to buy goods they previously purchased in stores — especially around Christmas, when UPS delivers more than 30 million packages per day in the week before the holiday.
The problem is that many of those package end up on unattended doorsteps, unlocked mailboxes and stoops. All this curbside commerce has created a new class of criminal dedicated to pilfering as many packages as possible.

A sneak thief who lived in L.A.
with packages oft got away.
The cops set a trap
involving dog crap;
that crook now is sure guano pay!
