@graf @sickburnbro @TrevorGoodchild I don't think that's right. I think it was after Lincoln that they took over protection.

That means they lost three (Garfield, McKinley, and Kennedy) and should have lost three more (Roosevelt, Reagan and Trump - they survived assassins getting through the protection). That's 6 losses out of 29. 20% failure rate is not very good, I think.
