Paris: Come on In -- The Door Is Always Open

The mission? Sneak on to Paris Hilton's property, crawl past the heat sensors and lasers and ... wait ... the door is unlocked? Cancel that -- just walk in and take whatever.

According to the LAPD, the reason it was so easy to break into Paris Hilton's fortress is because she forgot to lock the front door. It's not like this is the first time. Paris was also jacked in 2004, and thieves made off with $100,000 in Hilton accessories.

Times are hard for everyone -- but a Hilton.
