Online complaint, officer falsified a police report, his driving manner caused you to feel harassed, alarmed and distressed. ‘Aggressive braking’ is his opinion and wouldn’t be an issue given he had given you the legal requirement of braking distance. The fact that there were two of them in an ill equipped vehicle to even record your speed makes no difference. Don’t even listen to the advice of police officers on here because half the nitwits can’t do their own job. Ask for an official apology and a response otherwise it will be escalated to the IPCC. You will get a letter from the divisional commander of central division to address the issue. I’ve been this route more than once, don’t feel intimidated they are there to serve you and must follow the same laws we do.
