“We’ve seen this before in the area of video gaming where the gaming board after the fact would propose certain rules to try to close loopholes and the legislature shot that down,” Johnson said.

The Crime Commission sees an opportunity for organized crime involvement.

“When you’re dealing with the wild wild west of internet gaming those kind of problems can happen more readily. There’s less transparency here,” Johnson said.
