Who is responsible for which single act of violence can only possibly be of interest to those who have selected which particular side of the sectarian divide they are rooting for and wish to blame 'the others' for the trouble.
Violence takes place where and when it does each year because giant, provocative marches are allowed to take place throughout the North Eastern counties of Ireland at this time of year, and they do just that - provoke.
While they are allowed to continue, so will the violence, and due to the delicate political situation in Ireland today, they are quite likely to escalate into full-scale warfare again, as they did in the past.
