Historically Japan would have executed someone like this and that's not an exaggeration there have been examples in the past. Now is that too authoritarian? maybe .
But Johnny Somali (apparently he's Ethiopian by the way so he even lied about that and his real name is Ramsey Khalid Ismael and he really hates people knowing that for some reason so im putting it out there. ) being a public nuisance , disturbing the public constantly and insulting the country constantly and yet nothing can be done about it because he's technically not breaking the law.
Now imagine tons and tons of people behaving like Johnny Somalis/Ramsey Khalid Ismael and creating public chaos and nothing can be done about it cause they are technically not breaking the law.
Suddenly authoritarianism makes more sense
because ethiopians and somalians dont get along so he decided to pretend to be somalian
Maybe he is ethnically Somalian, but yeah, maybe it is because he knew his behavior is shameful and he didn't want that shame associated with Ethiopia.
