The series of photos below – culled fromIndymedia– show an apoplectic SWP member (the wad of unsold Socialist Workers is the clue) and a PSC official (with the bullhorn) accosting a marcher with a sign saying “No IDF / No Hamas” and destroying his placard.
The PSC official was apparently the Chair of the Sheffield Palestine Solidarity Campaign and he was supported by other SWP members who demanded the removal of the placard.
Apparently you can’t march for peace with the demands that both sides stop firing anymore.
