She should spend 10 years working for a soup kitchen first to get actually close to the people. Only then should she think about moving onto anything local.
People talk about going back in time to kill Hitler. College humor had a skit where they talked about why you'd have to do it as a baby, and the world would hate you as a kind of funny haha. Or maybe it was stopping 9/11? But imagine going back in time and killing Booth. Even right before the act. "Some guy just showed up and killed America's second favorite actor, right behind the president!" No way to spin it to them. "No guys I swear he was the bad guy"
Ridiculous. He wasn't president when the crime occurred, he wasn't president when the trial happened.
