I am sorry but I have to challenge this ... is there something wrong with that? same with table saw, circular saw, power nailers, wood
chipper, lawn mower, snow blower and power drills... All dangerous, one of which send more people to the IR then the chainsaw ... you know which one ? power nailer is the answer... what are you suggesting mandatory training before purchase so a home owner can't execute any dangerous task without training ?? Let me point out you guys (USA) don't even do that with fire arms.
