 Irungu Houghton is head of Amnesty International in Kenya, which sent observers to assess the military and police responses. It's been an extraordinary intense week in many ways, Paul. The observers picked up on a number of areas of police misconduct. There was, in some cases, excessive use of tear gas and shooting of tear gas canisters at quite short range. We had a number of injuries as people were hit by the tear gas canisters.
