I went to investigate the noise coming from the street and there are a bunch of protesters with noise makers and drums massing in front of the synagogue on Central right off Broadway. They have signs that read "Stop greed" and something about not shopping at Shaws.

What is this about, and why are they in front of a synagogue?
