Quote MessageWhat we have to do is reflect on what happened in Paris last night, about the way in which the attack took place. We'll want to know the people who were involved, we'll want to know the motive behind the attack and we'll want some very tactical things: Where did they get the weapons? Where did they get the ammunition? Is there anything we can learn in this country to either help the French in their bid to cut off that supply or make sure that neither the people involved or the weapons involved materialise on the streets of this city or any part of this country?"

Quote MessageToday, all our thoughts and sympathy are with the people of Paris. What took place in the French capital yesterday was horrific and immoral.

It's vital at a time of such tragedy and outrage not to be drawn into responses which feed a cycle of violence and hatred."
