Duggan: How police cameras are used in Slough

9 January 2014 Last updated at 12:12 GMT

The country's top police officer wants firearms officers to use video cameras from now on following the death of Mark Duggan.

The 29-year-old was shot dead by officers in Tottenham in 2011 because they thought he had a gun. His death sparked riots around England.

Thames Valley Police have been using the cameras since summer 2013.

Newsbeat reporter Nomia Iqbal went out with officers in Slough last year to see how they conduct stop and searches and how the cameras can protect both them and the public.
