The banking angle to the whole story is weird. So guy goes on a rampage, kills 4 people and the message he sent with his bank transfer is the story? The bank didn't tell him where they lived. He knew that already. The message - although on its own it would - was not the problem. Had it been, it would have been reason for legal action against him as it should be. He could have shouted his slurs at the house they lived in. What would it have changed?
