Maybe, it's very easy to say that from the comfort of your armchair. But his age changes the context of this a lot for me. Still not convinced the Mother has acted criminally reckless or negligent, but my comparison to a taxi driver earlier is obviously not cutting it.

We're judging this though from different countries. You, me, oskar, not one American. Guns aren't legal where we live, so our perspective on this is skewed compared to Americans, which include this guy's Mother. She's subject to their laws, not our moral standards.
