Only partly true there I’m afraid. Pennsylvania allows for children to be responsible for medical and long term care bills from their parents under a filial support law:

Many states have little to no rules on storage. You also don’t really need a license to buy one just to carry it concealed in public (some states don’t even require this step). Of the states that have storage laws like my own, I’m unaware of any that require you to prove safe storage though. The laws only offer a punishment after the fact when something bad happens.
