The medical marijuana industry in Oklahoma could mean big money.
The money is almost exclusively going to be cash and because of federal laws, federally insured banks won't touch it.
One Oklahoma man sees that as an opportunity.
Chris Collier owns Green Line Security and says his armored cars and armed guards will operate a bank for medical marijuana businesses.
“We are going to be operating a tradition bank branch with real vaults so people feel comfortable about their money being protected,” Collier said.
Green Line Security also plans to offer security at legal grow operations. They hire a lot of former members of the military.
