Why does Hegseth want the world to see a death by firing squad?

It has been nearly 100 years since the last public execution in the US but, on 3 December this year, that could change. The US secretary of war, Pete Hegseth, said last week that the execution of Nidal Hasan, the man who killed 13 people at Fort Hood, will be a public event – a claim that was later confirmed by a defence department official. On Saturday, the US president, Donald Trump, said he had yet to decide whether to let the livestream go ahead.
