Campaigners have expressed dismay that a policeman acquitted of brutality last month will be in charge of security at next year's G8 summit in Italy.
Franco Gratteri was one of those in charge during the 2001 G8 meeting in Genoa, which was marred by violence.
While he was cleared of related charges, colleagues were convicted.
Mark Covell, who was beaten unconscious by police at Genoa, said he feared police had not learned lessons and violence would flare again next year.
Genoa 2001 became notorious for violent street clashes between anti-globalisation protesters and police, that left many people injured on both sides.
Thirteen police officers were convicted last month in connection with attacks on defenceless demonstrators at the Diaz School in Genoa in 2001. But Mr Gratteri and several other senior commanders were cleared of responsibility by the judge. -- /link/
