Video appears to show unarmed black jogger shot dead by men who claim to be looking for a burglar

This video appears to show the moment two armed white men fatally shoot an unarmed black man who was out on a jog. The footage, which was taken by an unidentified witness, shows 25-year-old Ahmaud Arbery jogging down a lane and around a white truck. As Arbery crosses in front of the vehicle, a shot is fired. Arbery is then seen grappling with an individual before several gun shots go off. The two white men have been identified as Gregory McMichael, a police officer, and his son, Travis. They say that Arbery looked like a burglary suspect. The incident, which happened just outside Brunswick in Georgia, has lead to outcry on social media as people demand justice for the killing.
