Like many other kids, Trayvon had a Facebook account. Like kids his age, he post pictures and updates. None of that is relevent now that he is dead. The person that shot him didn't know about his Facebook account, so what does it matter. None of the things and events Trayvon did days, weeks or years leading up to his death are relevant unless the shooter had prior knowledge.
What does matter is Trayvon is dead, and a man that didn't know him or about his Facebook account was moved to action. In the article, How one man helped spark online protest in Trayvon Martin case, Kevin Cunningham read about the killing of teenager Trayvon Martin. Cunningham, describes himself as the “super Irish” learned about the Martin case when he read a story posted for Men of Howard. Cunningham joined the informal fraternity while attending the historically black Howard University as a law student. He had no idea his petition would reach so many so soon and so powerful. "The fact that more than 2 million people have signed this petition shows there are still a lot of good people in this world."
