"It was meant to be my own personal reflection on the situation and wanted to share my condolences. The shooter came from the same community that I did."
Hindes grew up in Baldwin-Whitehall, the very same community in which the 46-year old suspect lived. He shared the image on Facebook and in a few hours, it went viral.
"It really got to me," said Hindes. "I was driving down to my parents' house the day or two after. I saw four or five businesses along the way that had posted the symbol along an electronic marquee, on a yard sign or a chalkboard, that made me realize what the symbol had with others."
The next day, Hindes got a call from the Pittsburgh Steelers. The team wanted to partner with him to make sure the proceeds from any merchandise using the symbol would go back to the victims' families or anti-hate groups in Pittsburgh. More than $70,000 went to Victims of Terror Fund by the end of last year's Steelers season.
Hindes is humbled by how far-reaching the symbol has become. It's been shared around the world, like in Prague on the John Lennon wall. He hopes the message behind it is spreading as quickly.
"It's hard to measure the breadth of the impact of the symbol, I know it's been tremendous," said Hindes.
