My opinion on current events is sometimes influenced by my awareness of history:
It's mind-boggling that British soldiers from the 1700s were held more accountable than modern American policemen. If you're confused, google (or baidu or yandex) "Darren Wilson".
Related fun fact: if you are a visitor from literally any other country, you have a lower per-capita imprisonment rate than we do here. Putin's Russia? Communist China? Any random banana republic or middle-eastern petro-kingdom? Your government has imprisoned less of its citizens than mine has!
And we call ourselves "Land of the Free"!
