Seth Tobocman, the East Village radical comic book artist, was at the Republican National Convention in his native Cleveland, where he documented the goings-on in sketches, then put them out on the Web as part of the Comixcast protest group. At right is a drawing of Freedom Plaza, which had nothing to do with free speech, but was where convention-goers could guzzle beer, grab cheeseburgers and listen to live bands. Below is Tobocman’s depiction of an anti-police brutality rally that he attended outside the R.N.C. last Friday.
