Google can be your friend or make you look like you don't know what yuo are talking about:
One of many:
Man Arrested For Telling His Girlfriend He Was Going To Kill Bush Mar 3, 2008 ... Wanda testified in court that Charles had threatened to kill the president. ... to launch a criminal investigation into former President George W. Bush ... girlfriend his desire to kill the president has landed him in jail
There’s a difference between a credible threat and an infirm old man expressing a wish that we might not agree with. IMO, the fact that he SAID such a thing proves he’s probably not competent.
I sat next to seniors from 2003 - 2008 and listened them them telling me angrily how “Bush should be SHOT”. Nobody came and arrested them. They weren’t threats, they were opinions and wishful thinking.
