Although it is not an exhaustive list, the following are examples of the types of incident that are recorded: protests and demonstrations, photo shoots and external events, high-profile and VIP visits, concerns regarding members of the public within or outside the building, crimes that have taken place, arrests or detentions of people on campus, road traffic matters, and unusual or offensive correspondence. As for the number of incidents that have been recorded since 2012, I can tell John Wilson that in 2012 there were 145, in 2013 there were 180 and in 2014 there have been 79 to date.
