Michael Vick was back signing copies of his autobiography Saturday and said he would continue to stay "positive" and wouldn't let threats keep him from finishing his book tour.
A series of book signings for his new autobiography, "Finally Free," including one at a book store in Atlanta on Saturday, had been canceled due to threats to Vick and store employees. Vick signed books at an Atlanta-area church Saturday instead, an impromptu appearance that was set up in one day.
"That's a very small selective group of people who still have their own form of hatred," Vick said Saturday of those who made the threats, according to the Atlanta Journal-Constitution. "But you know, I think the most important thing for me to do is to continue to stay positive and continue to do the right thing because that's what's going to make a difference ... You gotta move forward."
All the profits from Saturday's signings were donated to a charity that works with young males serving time in detention centers.
The book chronicles the events around his conviction for dogfighting and his childhood in Virginia.
In an interview with USA Today Sports, Vick wondered why a select few people would "continue to bash somebody who's trying to help make the world a better place?"
Vick served 18 months in federal prison for his role in running a dogfighting ring that derailed his career until he returned with the Philadelphia Eagles in 2009. According to court papers in the cases of Vick and his codefendants, Vick, then the star quarterback of the Atlanta Falcons, bankrolled the operation and joined others in killing dogs that didn't perform well.
He told USA Today that he's not trying to "overlook what I've done, but I try to do outreach as a positive" and would continue his work with charity as "that's what's important," not those who decide to make threats against him.
Vick told USA Today that he wasn't so much afraid for his own safety, but had to take precautions for the people who had planned to attend his book tour signings.
"I knew a lot of people were going to be at the signings, and I didn't want to put anyone in jeopardy," he told USA Today. "I think the small fraction of people who are still making these derogatory comments and thinking irrationally, they're in a league of their own. But we won't let it stop us from what we're trying to do."
He also said the news coverage of his canceled signings only served to boost sales of his new book and he plans to finish the book tour even if he receives more threats, "but we'll do it in a totally different way."
Since his release from prison in 2009, Vick has worked with The Humane Society of the United States to speak out against animal cruelty. He had made appearances at schools and spoken to students about the dangers of being involved in dogfighting.
The four-time Pro Bowl quarterback agreed last month to a restructured three-deal with the Eagles to remain with the team.
