As an aside, why do you think the IPCC reports (especially the first one) were a whitewash from the IPCC?
The first one recommended PC Harwood be charged with manslaughter, and fairly conclusively demonstrates that the cause of death was most likely not what Patel claimed it was - in short it appears (based on the reports of what the inquest jury found) to have come to much the same conclusions as jury did in the inquest into Tomlinsons' death. Even the third one recognizes that an acting DI provided the wrong information to one of the subsequent post-mortems, albeit they were not able to prove that he had done so deliberately and maliciously.
