Cleveland Browns running back Isaiah Crowell issued an apology after posting a picture on Instagram that showed a man slitting the throat of a police officer. Crowell deleted the post. He has now issued a public apology after posting a note that read: "They give police all types of weapons and they continually choose to kill us….#Weak” "Last week was an emotional and difficult week as we saw extreme acts of violence against black men across our country as well as against police officers in Dallas," Crowell said in a statement. "I posted an image to Instagram in the midst of that emotion that I shouldn’t have and immediately removed it. It was an extremely poor decision and I apologize for that mistake and for offending people. My values and beliefs do not match that image. I am outraged and upset by the deaths of Alton Sterling and Philando Castile along with so many others. "I am also outraged and saddened by the attacks in Dallas and the deaths of the 5 honorable police officers (Lorne Ahrens, Michael Krol, Michael J. Smith, Brent Thompson and Patrick Zamarripa) who were providing protection while trying to keep peace. We have to be better as a society. It’s not about color, it’s about what’s right and wrong. I was very wrong in posting that image. Every single life matters, every death as a result of violence should be treated with equal outrage and penalty.” Follow me on Twitter: @AaronWilson_NFL Aaron Wilson covers the Texans for The Houston Chronicle.
