LONDON - British police flooded the streets to ensure weekend drinking does not reignite the rioting that swept London and other cities this week, shocking Britons and sullying the country's image a year before it hosts the Olympics. Steve Kavanagh, deputy assistant commissioner of the Metropolitan Police, said 16,000 officers, instead of the usual 2,500, would remain on duty in London in their biggest peacetime deployment -- a measure of the perceived public order challenge. Other forces, including those in the cities of Nottingham, Birmingham and Liverpool, said they would maintain a high level of policing over the weekend, although they said they were not anticipating further trouble after a couple of nights of quiet.
