I believe the quality of the video is a big deal because it was used as a fairly important piece of evidence against KR. Someone correct me if I am wrong please.
100% correct
The video shows the confrontation by Joseph Rosenbaum and his shooting. It follows a shot believed to be fired by Joshua Ziminsky. It was a shot that made Rittenhouse fearing for his life. Rittenhouse hears Ziminsky’s words that tells Rosembaum to get him and kill him. This is the incident that triggers Rittenhouse being chased and being cornered before Rittenhouse shoots him while he lunges at him. The enhanced video should show the evidence that will find Rittenhouse justified by self-defense.
