Oops, I misspelled a word on the message title for my previous response. I haven't heard of the 100th anniversary of McKinley's assassination in any national media, but I thought that it would be covered locally in the Buffalo area. Sure enough, I found this article on the Buffalo News website:
From the article, I you can learn about some of the remarkable ways that things have changed in the past 100 years. The assassin, Leon Czolgosz, was put on trial only 9 days after McKinley died, and it took only 34 minutes for the jury to convict him. Czolgosz was executed on Oct. 26, only 50 days after he fired the fatal shots at McKinley.
Also, did you know that Buffalo was the 8th largest city in the USA in 1901? Did the assassination of a US President in that year help lead to a decline in the city's population and influence?
