In 2009, G.F. Newman stated that he considered "90% of police to be corrupt at the time, and that there has been no significant change since then." For the series' thirtieth anniversary in April 2008, it was released on a limited edition DVD via 2|Entertain. In April 2018, BBC Four announced that the series would be rebroadcast on television for the first time to mark the series' fortieth anniversary. This statement was inaccurate, as a full repeat had previously been broadcast on BBC4 from 24 March to 14 April 2009 and it had also been repeated in March 1980. The 2018 repeats began at 10:00pm on Thursdays from 12 April 2018.
