With so many high-profile cases of cheating spouses making headlines, a North Texas spy shop is reporting an increase in sales.
But lawyers warn that while it's perfectly legal to buy spy gear, it may be illegal to use it.
"It all comes down to how you use the things you buy and what you do with the information," attorney Clint David said.
The Spy Centre in Plano sells everything a do-it-yourself sleuth needs to catch a cheater in the act. The shop has everything from gadgets to read deleted text messages off a cell phone to computer spyware and GPS tracking devices.
"The products we sell give people a piece of mind: 'Are they lying?' and, 'Are they going where they say they are,'" store owner Melissa Dear said.
But trying to catch a spouse breaking his or her marriage vows could mean breaking the law.
"The problem is, if you don't own the computer, phone or car, any spyware or interception of messages is a violation of privacy and/or wire-tapping laws," David said.
He said spouses have been sued for intercepting messages they didn't legally have access to.
