EXCERPT:
CHO: "You can you do you can do this, Bill. Look, this was $3.47 at Home Depot. It is a 'No Trespassing' sign. You could put this up in your front door, on your property line, somewhere where you can see it from the street. But this is the catch. Take a time stamped picture of the sign. Most iPhones do this automatically."
RITTER: "Yeah."
CHO: "Because what you want to prove to police is that the sign was up before the squatters moved in. You know what I mean? So you have to show that time and date stamp, that's also why video security is so important."
