Ever heard of a Suspicious Activity Report?

It is a report banks have to make when a large transfer of funds happen apart from normal business activities. So if you sold your bought and paid for house and put the money in the bank you would not get reported. If a Nigerian prince wired you 100 million to help him get his money out of Nigeria it would result in a Suspicious Activity Report. Funny bit of Trivia. President Trump has never had such a report even though he deals in large sums of money all the time. President Biden has over 200 such reports of money coming from foreign countries etc that have no basis in normal business activities.
