As protests are becoming more and more commonplace and their increased effect on stopping people from going about their everyday lives. Was it right when a few individual commuters took the law into their own hands and pulled a protester off a train. Do you think enough is enough and it is okay to fight back against protesters. Or, just because a protester went too far that it is unacceptable for members of the public to intervene and should this have been left to the authorities to deal with.
