During PC Simon Harwood's cross-examination by Mark Dennis QC, he was asked:
"You do now accept that what you did in relation to Mr Tomlinson was wrong?"
Harwood replied: "Like I said, now I do, but not at the time."
He went on: "Now I've seen all the evidence and I know how poorly Mr Tomlinson was I'm sorry that I got involved, I shouldn't have hit him with a baton and pushed him."
Harwood, 45, from Carshalton in Surrey, denies manslaughter on the grounds that he used reasonable force.
