I can't really understand why you'd refuse to comment on other equally entrenched barbaric out dated laws (and that is all they are) that cost citizen's their lives, whilst suggesting it's naive/misplaced for others to question equally barbaric, out dated laws in the USA.
I've not commented on stoning in Saudi Arabia as it isn't relevant to the thread about a toddler shooting other toddlers in the US, I've stated that already, I'm not really sure why you keep asking.
They just had to store their guns in a place where children cannot get to and it should have had the safety on, or keep ammo seperately..... Bad parenting or guardians nothing else....
indeed - but given the often general lack of requirement for firearm owners in the US to store their firearms safely this is where some legislation could help - laws re: storage of firearms and greater accountability for firearm owners would both be useful IMO
