Anger at 'song title' inquest evidence
The officer, known only as Alpha Zulu 8, has already been reprimanded for swearing during his evidence at Westminster Coroner's Court. He also allegedly used the phrases "first time", a hit by Robin Beck, "enough is enough", the subtitle of hit single No More Tears by Barbra Streisand, "point of no return", a Duran Duran hit, and "line of fire", recorded by rock band Journey.
An inquest jury decided Mark Saunders, 32, had been lawfully killed after an armed stand-off at his London home in 2008.
His mother Rosemary, who sat through much of the inquest, accused the officer of apparently treating it as a "game".
