Ryan Alan Hade was an American sexual assault victim from Tacoma, Washington.

Earl Kenneth Shriner was convicted of the attack and sentenced to 131 years in prison. Shriner had a long history of sexual assault charges spanning 25 years.

During an anti-globalization demonstration outside the July 2001 G8 summit in Genoa, Italy, protester Carlo Giuliani was shot dead by riot police as he and other demonstrators attacked their van, making his the first death during an anti-globalization demonstration since the movement's rise from the 1999 Seattle WTO protests. Photographs showed Giuliani, a 23-year-old Roman living in Genoa, throwing a fire extinguisher towards the van, a pistol firing a shot in return from the van, and Giuliani's body having been run over by the van. Charges against the officer were initially dropped without trial as a judge ruled that the ricocheted bullet was fired in self-defense, but the incident became a point of public scrutiny. The European Court of Human Rights, eight years after the incident, ruled that the Italian forces had acted within their limits, though damages were awarded for the state's procedural handling of the case. Appeals upheld the ruling, and Giuliani's family later filed a civil suit. Giuliani was memorialized in music tributes and public monuments, and is remembered as a symbol of the 2001 G8 protests. The 2002 documentary Carlo Giuliani, Boy, recounts the incident.
