I may have answered my own question. Everything surrounding Ian Tomlinson's death carries the distinct whiff of a cover-up.
Pressure is on Coroner Professor Paul Matthews to stand down from the inquest as it has emerged that, not only did he appoint Dr Freddy Patel at the request of the Metropolitan Police (a not disinterested party at the time) — a discredited pathologist who was already under investigation by the GMC — he also banned the IPPC from attending the post mortem. On top of which, he failed to advise Ian Tomlinson's family of their right to attend or send a representative, or inform them of the date and time of the procedure.

Dodgy all round. Discredited pathologist and unbelievable CPS decision not to prosecute PC Simon Harwood. No police charged in Ian Tomlinson's death at G20 demo.
