A slop-pail is the symbol of solidarity of criminal mafia, the one who violates the gangland laws risks to see the bottom of the slop-pail. Nobody will squeal on those responsible for rough justice. When there are 200-300 people in the «mass cell» even vertuhais (prison guards) don't dare to interfere. The eyewitnesses never see anything. Otherwise there is no hope of rescue for them whatever prison they would be transferred.
