The parents caused it by raising incompetent fools. The immature young men could have caused their own deaths in many equally stupid ways (drugs, driving stupidly, playing with nail guns, etc.).
I agree, but lawsuits like this if allowed to proceed will cause tremendous damage to Cabela’s and eventually anyone else involved the firearms business....
I have 7 kids. They were all raised around readily-available guns and taught gun safety. No problem.
