50,000 people visit Camden Town each Friday and Saturday evening. This is equivalent to the crowd at a Premier League football match. Camden Town have a dedicated Police team of 6 officers on duty as well as the usual SNT team.
At a "category A" football match with 50,000 fans in London there would typically be 150 police officers. There would also be 200 stewards. Football crowds are usually easier to police. The majority of fans are home fans who know what the best routes are and what the police will worry about. They follow the same routes every 2 weeks or so. Many night time economy customers come only once every 3-6 months and are going to different places and don't have such an understanding of how to move around the area. Given this much lower policing ratio, is it any surprise that the streets of Camden Town (and other areas of London affected by night time economy crowds) see the level of incidents and anti-social behaviour that they do?
