Soon after he shot three people, a panicked 17-year-old Kyle Rittenhouse told a friend he expected to go to jail for life, but that if he had not fired, he would "probably be dead."
Self defense for sure. Afterwards he realized they were going to railroad him and he was scared. And he was correct, they are railroading him and he should be scared. So far absolutely nobody seems to have his back at all.
