And the most ridiculous response goes to Representative Cotton from Arkansas: “Sic semper tyrannis." I can't imagine the logic that goes through people who use this language. It clearly hearkens back to the assassination of Lincoln, which seems to me to imply that you have at least positive feelings towards his assassination.
Booth was a very famous actor and had a known.... flair for the dramatic. So yeah, it makes sense that he would throw around Shakespeare quotes while killing someone. Oddly, I'm not sure that he fully 'got' the tragedy of Brutus and Cassius. Maybe he stopped after Act 3 and figured it all worked out for the assassins.
yes in america it has that connotation http://en.wikipedia.org/wiki/Sic_semper_tyrannis There is a strong anti-american trend in the conservative party.
