How property owners and lawmakers are turning the tables on squatters

When Flash Shelton found squatters in his mother's home in Northern California five years ago, he figured out how to work around a system that often appears to protect the squatter and not the property owner: he decided to turn the tables on the squatters.

"These people feel like the law allows them to do it, so why not me?" said Shelton, who has become known as "The Squatter Hunter."

Shelton is now hired by property owners to target squatters living in their homes without permission. Property owners start by giving him a lease, with the legal rights that come with it.
