Blair Peach 1979. Ian Tomlinson 2009. No Justice, No Peace.

In 1979 they called them SPG. They got such a bad name for violence, arrogance and untouchability that they changed the name to TSG. They changed nothing else. Thirty years on we still see the same failure to control police violence as the massive cop who batoned Nicola Fisher walks exonerated from court. Back in '79 the cops who killed Blair weren't even charged.

And thirty one years on, the policed still cry for justice. Here Julia Tomlinson, Ian Tomlinson's widow, weeps as she lays flowers with other family members at the spot where Ian died after being attacked by TSG officers.

And after getting on for forty years in this job I'm still walking home with the voices of the bereaved echoing in my ears. "No justice, no peace. No justice, no peace."
