You can say it as many times as you like!😅 It doesn't make your argument meaningful. There is no law against travelling right across America! If somebody attacks you when you get there and you defend yourself, there's a good chance that it will be considered self-defence in a court of law.
Nobody is selling you a self-defence argument, so there's no need for you to buy it. But it is the verdict that was reached by law. And it was the correct verdict in this case. You can dig your heels in, or you can take the time to understand why. It's up to you.
