Well, this is not entirely accurate, the video shows a woman who was arrested/assaulted/kidnapped by an undercover police man (? no Memorandum Rights rights read), whilst outside the bank. What was she arrested for? What crime has this woman committed? Taking a list of names/communicating with those detained (so that they can be legally represented?) isn't a crime.

Was this actually an undercover police man or was he a Central Intelligence Agency agent?

There are many unanswered questions here, but there does appear to be a truism being displayed by this financial institution in that the bank is prepared to close its doors and no pay monies owed in the event of a future bank run most likely citing the possibility of civil disturbance (even though the banks customers will have queued peacefully to get their money).
