Yeah, cost her. It's a tragedy and I'll feel bad about it to see people hurt by stupid decisions. However, if I were to buy a gun I'd lock it up in a safe, possibly with finger-print access and in my bedroom, and be sure to keep it from children. That's a price of giving power to people. Some people are idiots. Some people make stupid mistakes. Some people do stupid things. We should seek to protect them and help them, not dismiss them as stupid, but we shouldn't seek to protect them from their own stupidity. Arrogant idiots exist, but honest kind and intelligent people far outnumber them in both number and outcome. It's why liberal and free society is better than ones that attempt to restrict human nature and power. Human nature and power is good, not bad. Perhaps this would be a good ground, as well as cars, from which to speak of gun control? Imagine if those who abused guns or were in stupid situations were treated as those who abused their rights to alcohol? Place gun control on those individuals after they act stupidly. But none of the drives to fix them that we do. Our mentally ill will shoot us dead. Our race riots can turn into race wars. We are not without teeth, and that's a great thing.A little humbleness or humility would have likely caused that woman to think twice about leaving a handgun out that morning because she would have understood that if something could go wrong she would have a dead child. Evidently her arrogance cost her.
It's the same bulllshit arrogant mentality that makes people believe they are just good at driving drunk and that they are above the law.
Other countries have mental health problems, underfunded social programs, poor people, drug addicts without the ridiculous gun violence problems yours has.
