It was staged anyone with medical trauma experience knows you dont out a double amputee in a wheel chair sitting up. People suffering massive traumas do not sit up and pose for pictures and blood coagulates and oxidizes very dark after a short time exposed to air even heavily originated arterial blood turns a dark dark brown after a short time. The blood on ground was Hollywood fake blood as it persisted bright red. Biggest giveaway was the wheel chair "victim" no true trauma responders would put him in a wheel chair and his complexion given true blood loss would be very pale he had a healthy complexion entire time.

You all watch too much Hollywood that was fake.
