Kyle turns himself in to the cops.
Do the cops do anything to help him?
Do they investigate the case?
No, they just say, oh, hey thanks for doing our work for us by turning yourself in, now have a nice life in jail.
Do they do anything to assist in establishing that the shootings were in self defense? Anything to assist in proving that Kyle was the victim who was able to save himself no thanks to them.
All they did was spray him with pepper spray.
