If I get too detailed on some things that are personal like that, it gives people an easier way alienate themselves from me and that's all they are looking for now." --Time interview with McVeigh, A Look Back in TIME: Interview with Timothy McVeigh TIME's Patrick Cole talks to the defendant in prisonThis was my first hint. I found this comment after 9/11 and I haven't stopped thinking about what it means.
