Temporarily caught up in the freedom concept, that quote caught my attention.
One man's terrorist is another man's freedom fighter
"The Yale book of quotations" by Fred R. Shapiro lists this quote as coming from "Harry's game" by Gerald Seymour in 1975 as opposed to some of those who have used the quote later without attribution. "Harry's Game" is described as "A British cabinet minister is gunned down by an IRA assassin, leaving an undercover agent to track down the killer before he himself is killed." To put the quote more in context.
This has become a topic of discussion and even research papers.
