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
Nobody voted for the mass immigration policies imposed across the entire West and now increasingly Japan too. Hell, even California voted against gay marriage when given the opportunity, and Japan would likely have done the same if a vote was held on the matter. But the judicial & political establishment (as if there's a difference at this point) decided actually no, your vote doesn't count if you vote the wrong way. Or in Japan's case, to just skip the show vote entirely (presumably to avoid another Prop 8-esque embarrassment) and get their pet judges to mandate it immediately at Rahm Emanuel's command.
I would gladly take the blunt dictatorship of Sulla or Cromwell or Hussein over what we have now. At least you could trust those guys to be honest about being dictators, they wouldn't insult my intelligence by pretending to give me a choice in whether or not to participate in my own slavery.
japan needs the shogun to come back for a bit and sort shit out.
