Any business owner understands this. You can do what you want provided you send octuplecat paperwork to 5 agencies along with a copy of your birth certificate, passport, a proof of life photo, and your pinky finger. Once that's done we will do an environmental impact survey, you need to surrender your credit cards to Serbia, do 7 billion Hail Marys in Esperantu and then we can schedule your hearing for 2063. And then you can sell a sandwich. Presuming you cut the check to pay for all this up front.
That's called regulation. When they tout common sense legislation they mean to turn the little guy who just likes shooting a round of skeet into the same class as a chemical company, an aircraft company, or a hazardous metals supplier.
Great job guys, you have turned the right of self defense into a paperwork exercise. You know who sucks at paperwork? The battered wife on the run. The migrant worker unsure of the safety of his family. The honest man whose crazy ex wife started throwing accusations. Get down in the mud and the blood and realize you might be putting kids at risk because mom really needs a shotgun.
