It could have been considered an offence was committed at the time because of the word 'insulting' in the Act.

To call a police officer a **bleep** may not be abusive but could be insulting, however the word has since been removed from the Act as being detrimental to free speech.

Threatening or abusive speech can be recognised by most people whereas what may insult one person may mean nothing to another, if I had a heated argument with an MP and they called me a **bleep**, I don't think I would give it a second thought.
