The "tolerant left"

The Guardian reports that:

"More than 100 anti-fascist protesters are staging a noisy demonstration outside BBC Television Centre about British National party leader Nick Griffin's appearance on Question Time later today.

By 3.30pm, about 150 protesters had gathered outside the main Television Centre reception on Wood Lane, west London, chanting slogans including: "Build a bonfire, build a bonfire, put Nick Griffin on the top, put the Nazis in the middle, and burn the fucking lot.""

Is that chant "incitement"? Have the police taken names?
