The attack occured in front of about 20 people, none of whom stepped in to stop the assault.

It should be noted that photographer Stephen Parker was one of those who did not stop in to stop the assault; instead he took photographs of it. So, while clinical psychologist Barry Kirker might attribute the crowd's passivity to "bystander apathy'' - a phenomena [sic] which [sic] has been studied since the 1950s - the photographer might be accused of callous opportunism. On the other hand, every one enjoys a good fight.
