you say that in jest, but this event did expose that we (especially geriatric legislators) are not prepared to tackle a "social media" climate. 10 years ago neither could this Prisoners dilemma have taken place, nor could so much money have been physically drained in cash minus online banking.
Other banks don't have a tight nit group of customers so bank runs don't spread as quick.
Most, maybe all, banks don't have enough funds to cover a full on bank run because almost all treasuries bought over a year ago are worth less than their original value.
