I would assume both, unless the idiot that tries to get away with a bank robbery is politically motivated.
Not sure if the blue ones would not have any armed guards or would be heavily armed like the left's security details usually are...
Or would the blue ones have some socialist aspect and simply redistribute based on "need?"
I'm guessing the red ones would have armed tellers/managers/maintenance workers in addition to any security people. Not by policy, just because FREEDOM and/or 'Merica.
