[UPDATE BELOW] The tolerance shown by the NYPD last week towards the group of Occupy Wall Street protesters sleeping across the street from the NYSE evaporated this morning, as police cleared the sidewalk on Broad Street. According to the Times' Colin Moynihan, the order to vacate was given at 6 a.m., and for the next few hours police corralled the 100 or so protesters up the street so the sidewalk could be power washed. Four were arrested in the process, and one protester was punched in the face by an officer after he swung a bag at an NYPD camera documenting the action.

For now, the protesters seem to be congregating at Federal Hall across the street, which is open to the public until 5 p.m. It's unclear whether the protesters will be allowed to return to the sidewalk per a court ruling from 2000 that allows protesters to sleep on the sidewalk provided they don't obstruct half of the walkway.

Because tomorrow is tax day, Occupy Wall Street has a series of events scheduled to highlight New York's largest tax dodgers, including Bank of America, Wells Fargo, GE, Bain Capital, JP Morgan Chase, and Verizon.

The action, organized in part by United NY, begins at 11 a.m. in front of the James A. Farley Post Office, before moving to 725 5th Avenue, where Donald Trump is hosting Ann Romney for her birthday. According to a release, "A giant inflated mitt will be there to represent Romney, and the Tax Dodgers will hit giant inflated baseballs through the different loopholes."

[UPDATE] There has been a call for Occupy Wall Street supporters to converge on the site where the protesters were removed this morning. Via Twitter, Das Racist is also promoting the move.
