I don’t get the responses here. The not great idea of posting it on Twitter aside…
I’d like to know the situation on where this vehicle is, but if she indeed got it from a military vehicle, clearly it was indeed left unattended and accessible to people. That is a problem. So if she took it to hold and return, all yours fears of getting jammed up by the law aside, which I don’t think she will, it seems she did act in good faith and was far more responsible than whoever left the rifle.
She said she conceal carries, so it does seem like she’s some anti gun leftist.
Surely some will ill intent finding it would be the worst outcome.
So if that was left somewhere in public or on her property, I don’t see how she did anything wrong.
