Sure they can. And when the jury hears that gun store sold 850 guns that were eventually recovered in crimes in Chicago, they can draw their own conclusions.
You see, there's a reason why your iron has a label on it that says, "Do not iron clothes while wearing them". Because some idiot did that, burned himself and sued the iron company.
The background checks are inadequate.. that's the point.
If they had done an adequate background check on Joker Holmes, they'd have found out he was mentally ill and his university was in the process of throwing him out. NOT the kind of person you'd want to sell an AR-15 and a 100 round magazine to.
But he didn't have to. He just picked up the gun she left out for easy reach and shot her with it because she was going to put him in a home.
I disagree.
If an iron company puts a warning label on an iron due to a frivolous lawsuit, that does not show there should be more frivolous lawsuits, but fewer.
Irons get a lot hotter than people realize, especially how the steam penetrates the cloth.
But no one can fail to recognized the deadly nature of firearms.
Background checks are not inadequate, but our health care system is.
Before Reagan gutted our mental health care system, we did have much better means of recognizing the mentally ill and placing them under supervision.
Background checks just get the sellers access to the databases. That is not the problem.
The problem is no one wants to spend money on James Holmes, who clearly had to always have been totally crazy.
Everyone must have known he was crazy for years.
He was taking prescription drugs that are known to make people dangerous.
But none of the person's medical history gets into the background checks, because that would cost too much.
And I think you are mixing up cases.
James Holmes of the Aurora shooting did not get firearms from his mother, she was not in the process of throwing him out, and he did not shoot his mother.
The Aurora shooting is perfect evidence of how our for profit medical system is at fault, nothing else.
There was no one willing to pick up the cost of institutionalizing Holmes, even though it was obvious to everyone he should have been.
