Throwing a gun away in a publicly accessible trash can near a school is not responsible firearm handling, even if it is to prevent someone from suicide.
From the first line of my source:
"On Oct. 23, 2018, President Joe Biden’s son Hunter and daughter in law Hallie were involved in a bizarre incident in which Hallie took Hunter’s gun and threw it in a trash can behind a grocery store, only to return later to find it gone."
If the gun is Hunter's then it his responsibility, always. If someone other than the registered owner gets your gun and commits a crime with it you are still legally responsible unless you've reported it stolen. Obviously you have no clue about responsible gun ownership.
Furthermore, are you saying that Beau's widow is not "family"? A daughter in law is still family, albeit extended family, even if separated by death. That's how it works in my family and all the way up to high profile families like the Bidens. Ever heard of the Shrivers being called part of Kennedy clan?
Two other gems from my source:
"Hunter responded “no” to a question on the transaction record that asks, “Are you an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance?” Five years earlier, he had been discharged from the Navy Reserve after testing positive for cocaine, and he and family members have spoken about his history of drug use. Lying on the form is a felony..."
and this:
"At one point, two of Janssen’s employees, described by the police report as “Mexican males,” walked past the loading dock area, and Hunter told a police officer that the store had some suspicious people working for it. Asked if he was referring to those two staffers, Hunter responded, “Yea, prolly illegal,” according to the report." NICE WORK HUNTER, CAST ASPERSIONS THAT ALL MEXICANS ARE ILLEGAL!
Back to your point, my source quotes Hunter, but it's only his word about the possible suicide, not Hallie's, so it's obviously just conjecture on Hunter's part "When the officer asked Hunter whether he had been doing drugs or drinking heavily, he responded, 'Listen, it isn't like that. I think she believes I was gonna kill myself,'"
I provided a source. You obviously either have a reading comprehension problem or you have a better source. If it is the latter then please provide it if you can. If you cannot then I'll assume that your problem is the former.
