With hindsight, I can't see the point of running a complaint against the police for having f.cked around with your life, unless there's some money in it. Suing them focuses the mind on whether your complaint is useless or not. If it's half-baked, better not waste anybody's time. The IPCC's ostensible user-friendly face and glossy brochure sucks the daydreamer, vainglorious or purely hopeful in, only to spit him out. The only reason to justify an appeal is to suck a little bit more information from the police than they might otherwise divulge, but that only if you have the courage of your convictions to take it on to court. Beyond that, I agree with Bat-tat's opinion, that they are a waste of time.
