I work around Vauxhall and commute from streatham so travel through some fairly busy streets connecting Brixton Prison and police station to town. I've noticed recently a huge amount of Group 4 prison vans. Quite often there's a lunatic or two shouting and banging on the sides. Today on Durham street there was a massive wagon and it was literally rocking with blokes banging on the side and screming at anybody who comes past. Kind of scary and a bit funny at the same time. Anybody else see is craziness?
