Ian Tomlinson collapsed at the G20 protests two years ago The jury at the inquest into the death of Ian Tomlinson has retired to consider its verdict.
Jurors must decide whether Pc Simon Harwood acted illegally and directly caused the death of Mr Tomlinson at the G20 protests in London on 1 April 2009.
As well as unlawful killing, the other verdicts available to the jury are misadventure, natural causes and open.
Mr Tomlinson, 47, collapsed and died after he was hit by a baton and pushed to the ground by the officer.
Judge Peter Thornton QC, summing up at the inquest, said the jury had to decide if the baton strike and push were “unlawful” and “dangerous” and whether they inadvertently caused Mr Tomlinson’s death.
The judge said the push on Mr Tomlinson did not have to be the “sole or principal” cause of death for jurors to return an unlawful killing verdict.
The jury has been told the Crown Prosecution Service could review its decision not to seek charges against police officers depending on its verdict.
The month-long hearing at the International Dispute Resolution Centre in Fleet Street, central London, has heard Mr Tomlinson fell to the ground after Pc Harwood hit him on the thigh with a baton and then shoved him from behind.
Mr Tomlinson, who was not part of the G20 protest, got back to his feet but collapsed and died minutes later.
