 I'm sorry, they've got some serious questions to answer. Because you go in, you look at the threats, you look at the distances that weapons can obviously be engaged from, and you make sure there is a concentric circle going further and further out to make sure that you negate that possibility. The fact that that man could gain access to the roof draws a huge amount of questions. If they say that there was a lack of resources, it just takes an armed police officer to be on that roof to make sure that roof is never used.
