Italian police sentenced over 2001 G8 protests
During the G8 summit in 2001, police were accused of posing as "Black Block" anarchists (among others) and inciting violence. There was also widespread illegitimate arrests of protestors, beatings, alleged torture and inhumane treatment. Police also killed at least one 23-year-old protestor at point-blank range (self-defense was claimed and no charges laid).
It is not expected that any of the guilty officers will actually serve any of their sentences as the statute of limitations will almost certainly expire before the appeals are done.
