Bang goes the theory programme

Link below to a BBC TV programme about crowds. Seems to make a reasonable attempt to engage with current evidence, but it tries to cover such a massive range of issues across the board that they don't really get the chance to do justice to each topic. Best bits are the first 5 or so minutes looking at the psychological processes involved in football and protest crowds and about 14 minutes in that look at the physical pressures involved in crowding at concerts
