2. LeBron James and the Miami Heat, 2012
In 2012, following the shooting death of Trayvon Martin, Lebron James and his Heat teammates posted a photo of themselves cloaked in hoodies, much like Martin was prior to his fatal confrontation with George Zimmerman. James went even further, writing “R.I.P. Trayvon” on his sneakers during one game. James would engage in a similar demonstration a few years later when he would wear a shirt saying “I Can’t Breathe” to commemorate the death of Eric Garner.
