The BLM protesting shitheads were not peaceful. They were destroying Kenosha and tried to kill Kyle.
As far as smart gun handling Kyle is the envy of the gun community.
He effectively engaged attacking bad guys while being on the ground without any collateral damage and he did it while having to use a forward assist in the mist of battle. He chased away one shithead, killed two more assholes and disabled another dickhead with only eight shots. In combat there are generally thousands of shots fired for one casualty.
The next series of deaths are on your head.
