The scamming of seniors in the US is about 10 billion dollars a year
Only one in 20 report it. It is wise to be politely paranoid and not believe your child or grandchild is asking for immediate cash due a fearful, desperate or unusual incident. With scamming tools, the name and phone number may be correct. Getting duped is 100% initially but putting a halt to it before you hand over cash is possible. With AI we are seeing a doubling of these kinds of scams.
Don't be embarrassed that you do not disbelieve the voice of your child or a known authority.
