What rules?
They don’t specify in the video clip, but you can bet the enactment thereof will simply make it easier for the State to deny applications.
The statists/rinos are upset that an organization like Wisconsin Carry can train several hundred people at once on the legal requirements and basic safety rules. There are also a number of trainers who charge considerable fees that are unhappy with Wisconsin Carry doing it for free. I understand that one of the restrictions is on the number of people in the classroom.
