Sounds like she's gonna run for office. Uses her situation to push an agenda, even though it's reaching.
Sounds like she blames the daughter's military spouse for not locking the gun away so the daughter couldn't access it.
Also, how common is it for someone who commits suicide with a gun to aim at the back of the head? Usually it's in the mouth or to the temple on the side in which they would hold the gun. Even if you turn your head, guaranteeing you have a sure and lethal aim point will be harder. If not having an open casket is a consideration, a round to the chest/heart is also popular.
What wasn't divulged is whether her daughter had a history of depression, mental illness, or suicide attempts. If so, and the spouse knew, then a case can be made for keeping the gun "safely stored and locked away." However, to assume an unlocked and loaded gun was the CAUSE of the suicide, not her daughter's state of mind, is just pure rationalization.
It's been ruled in court that laws requiring guns to be locked away are unconstitutional. Some states bypassed that by placing the welfare of minors (living or routinely visiting there) above 2A rights. With the new viewpoint via Bruen, that "safety first" justification will likely be challenged again.
If these people were really about safety, they would push for firearms training in public schools. Kids who are educated are usually safer and less likely to "play" with guns once they are exposed to them on a range. They are also more able to protect themselves at home should an emergency situation arise,
