I fully agree irresponsible people are getting access, but this goes beyond firearms and training. There is irresponsible ownership and use, and then there is putting a firearm in the chest of a child, right after removing a loaded mag and pulling the trigger. Using my car analogy - there is irresponsible not wearing a seat belt, and then there is putting a kid on the roof and going off roading. First one - training, laziness, responsibility and access issue, second one is straight up murder.
