In the wake of the tragic shooting in Dallas that left five law enforcement officers dead, New York Knicks forward Carmelo Anthony took to social media Friday morning to ask athletes to "step up" and "demand change" without resorting to violence.

"Shooting 11 cops and killing 5 WILL NOT work," Anthony wrote on Instagram. "... I'm calling for all my fellow ATHLETES to step up and take charge. Go to your local officials, leaders, congressman, assemblymen/assemblywoman and demand change. There's NO more sitting back and being afraid of tackling and addressing political issues anymore. Those days are long gone. We have to step up and take charge.

"We can't worry about what endorsements we gonna lose or whose going to look at us crazy. I need your voices to be heard. We can demand change. We just have to be willing to. THE TIME IS NOW. IM all in. Take Charge. Take Action. DEMAND CHANGE."
