What police officers in Britain's do inside the royal palace

For those who were earlier shocked at the separation between Princess Diana and Prince Charles, and some of the lurid tales of affairs and other such juicy stuff that was revealed over the years. However, the concept was still that the Palace was a serious place, and that everything over there would be formal, and maybe a bit boring. However, if you read about the antics of some of the police inside the Palace, you would find that things can get pretty interesting inside the palace (link to article):

Police officers responsible for protecting the British royal family handled firearms when drunk, traded pornography and steroids and sat on Queen Elizabeth II's throne in comical poses, it has been alleged in a London court. At one point Cooper "suggested" there had been a procedure among armed officers at the palace whereby one officer on duty would sleep while the others kept watch for their superior.
The court also heard that officers protecting the royals lost more than £250,000 ($365,800) to a spread betting venture called "The Currency Club," one of a number of apparently successful sidelines Page allegedly set up to clear spiraling debts, PA said. Cooper suggested that McGregor had been "one of those police officers" using mobile patrols to deliver cash to other police officers based in Royal Protection who were involved in financial matters.

The image of police and that of the palace has been totally serious in the past, but maybe no longer.
