I find this story from Adbusters disturbing.

Twelve Occupy Philadelphia protesters were arrested on November 18,
2011 when they staged a sit-in inside a Wells Fargo branch to protest
the company’s blatantly discriminatory practices and “racist predatory
lending” policies which caused a large number of home foreclosures in
Philly’s African American neighborhoods.
On Tuesday March 5, the Common Pleas Court jury acquitted all twelve.
On top of that, Judge Nina N. Wright Padilla was eager to shake all of
their hands in support and recognition. She told them, “I hope you
continue your work in a law-abiding way, [and] I must say you are the
most affable group of defendants I’ve ever come across.” Further, the
Jury acknowledged that the protest served a “greater good” for society
that outweighed the trespass charge. This is a serious triumph for all
Occupiers, activists and protesters – who recognize that their tactics
may and will cross the line at times, but for the greater purposes of
justice, freedom and truth. That the judge recognized this is a major
coup.

Never mind what we can or cannot prove regarding predatory lending or free will, personal responsiblity, or the nature of power within the context of a major banking corporation. I find there to be an implication that the lobby of the bank is a public place despite its status as private property. Even then loitering has limits, yes?
