What's hilarious about the comment before me is: "that's why I also loved the paramore band bec. of their deep and very meaningful meanings of each of their songs" paramore didn't even write this song. Its a U2 song.
And actually. Its about Bloody Sunday, what happened in Derry, Northern Ireland on Sunday, January 30th, 1972 between Roman Catholic civil rights activists and the British army, when 27 Irish were shot, and 14 were killed.
