Two men came under fire in 2013 for dressing up as George Zimmerman and Trayvon Martin—complete with blackface and a bloody hoodie—after a photo of their Halloween costumes circulated online.

Many criticized the men for trivializing Martin's death, including Grey's Anatomy actor Jesse Williams who sounded off via Twitter:

Zimmerman, 32, was charged with murder for fatally shooting Martin, an unarmed black 17-year-old, in 2012. However, a Florida jury acquitted him in 2013. The verdict sparked national outrage, and helped propel the #BlackLivesMatter protest movement.
