Radio 4's excellent File on 4 has been investigating Deaths in Police Custody. The programme will be broadcast at 8 pm. It appears that a new putative disease has been invented in America and may be adopted here as a means of explaining away/excusing/covering up improper use of restraint techniques by police. The new 'diagnosis' is called Excited Delirium. File on 4 has also found that official figures understate the number of people who die in custody after being restrained by police."It discovered that anyone who dies following restraint without being formally arrested is excluded from death in custody figures. Campaigners want an inquiry into how the the Independent Police Complaints Commission (IPCC) collates its figures."
