““OFFICIAL ESTIMATES SAY THAT BETWEEN 1,000 AND 1,500 people sleep rough on the streets of London on any given night. Many of them are young runaways, fleeing abuse of various kinds at home. Some are elderly, people at the end of their lives who have lost everything. Quite a few have mental-health problems, made worse by the impossibility of getting their required medication. All are vulnerable; always cold, always hungry, slowly getting more weak and more scared.””
