The Daily Express reports, here:
Serving officers in terrorist hotspots including London and Birmingham said that forces are becoming increasingly nervy over the rising threat of Islamic State (ISIS) inspired attacks, with some telling staff not to wear their uniforms in their OWN patrol cars. ... [F]ear of Islamist extremism within Britain’s police is widespread despite the protestations of the authorities. ... [An] officer with Lancashire police said that officers have to “contact local community leaders to get their permission” before they are allowed to patrol in Muslim areas of Preston. And a policeman posted in Yorkshire said police top brass were so afraid of potential terrorist attacks he had been ordered not to wear police uniform in his own patrol car. ... Meanwhile in an interview last year Tom Winsor, Her Majesty's Chief Inspector of Constabulary, warned that there are “cities in the Midlands where the police never go” because local communities refuse to engage with law enforcement.
