The march for Trayvon Martin in Toronto, Canada, a teen shot over 1 month ago in Florida. The event was held on the same night as "Earth Hour". As the night got darker, marchers were given light sticks in fluorescent colors. The event started outside Toronto City Hall and ended by the US Consulate a few blocks down.
The slogan was: "Keep the light on for Trayvon, keep the fight on for Trayvon".
Used flash but reduced exposure later to make fluorescent light sticks stand out similar to the lighting at the scene.
