Australia

I take your point.

However, live-streaming the murder (which is what capital punishment is) of a murderer can reinforce that :

• the US is a violent society which is devolving back to more primitive times when hangings, lynchings, and other executions were used as public spectacle
• this sort of event is put on to make the US govt look strong but only makes it look decrepit trying to distract its people from the economic mess it's put them in
• it is creating a martyr which could lead to more people becoming radicalised and carrying out more terrorist acts on US soil and elsewhere
• the US is on par with the few countries that still have public executions like North Korea, Afghanistan and Iran, all of which are religious or political extremists.

You also have to consider that sadly and horrifically, mass killings of innocent people are common in the US but this one is being showtimed because it suits the political stance of the Trump govt. This both exploits the situation for political gain but also exposes that the govt is willing to traumatise not only its own people but the international community, and so losing even more respect.
