Cyclist assaulted on Chelsea Embankment

The IPCC are useless- I almost got knocked off by a police van, I filled out the form and sent it in, then got a phonecall.

• Is that Mr Dammit?
  
• Yep
  
• It's Sergeant Pepper, I have your complaint here, but I am afraid that the registration plate you gave is for a Royal protection vehicle
  
• Erm, so?
  
• Well, there's nothing further we can do I'm afraid, it was clearly not that van
  
• I'm sorry?
  
• You cannot have got the reg right
  
• But that reg does belong to a police van?
  
• Oh yes, but it was Royal Protection, so it cannot have been them
