I think the point you’re making is that he used violence to coerce the bank.
To OP’s point, he was only asking for his own money back, whereas a robbery is trying to take someone else’s money. I guess it all depends on the bank agreement and procedures during a bank run or a default. Sure, you get a statement that says you’re credited with $210k, but you don’t actually own that much money anymore if the bank lost some of it and can’t pay everyone their full balance.
It doesn't Have to include threats of violence or acts of violence: It simply usually does.
It does Always include theft of goods, though. This man wasn't stealing things, but rather trying to get his own cash. Despite the violence, this wasn't robbery.
