Video: Boris Johnson: In my book, you shouldn't abuse police The Mayor of London, who has previously stated that anyone who swears at police should face arrest, said: "In my book you shouldn't abuse police officers and I've made that clear loads of times. The crucial thing for me is that Andrew Mitchell has now apologised not just once, but twice. He's also apologised to the police officer concerned and that underscores how wrong it is for any us to abuse police officers when they're just getting on with their job. "This has been rattling on for quite a few days now," Mr Johnson continued. And I hope the message that people take out of it is that this is a serious thing to get wrong.
