Trying to leave the country just gives cops more authority to gun him and a few bystanders down.
If he's just at home chilling like nothing happened then all they can do is charge him with murder and send it through the legal system. Then they pretty much need the CEO solution device or like a manifesto or they'll have a real hard time getting a jury to find him guilty.
This has literally 0 impact on what I was taught in US public schools. It was already "victims of communism" parroting to begin with.
