Notice of Intended Prosecution. Oh. Fantastic. We accuse you so you are guilty. If you are not guilty, you must tell us who is. If you don’t know who is guilty, we’ll assume you’re lying and fine you anyway (and it’ll be more than the fine you’d get if you were guilty). You have the right to silence, but anything you don’t say will be taken as an admission of guilt.
OK, so I was speeding, and I will pay the fine. It doesn’t make the tactics any less derisable.
