Friday's "20/20" had a jailhouse interview with psycho fireman-impersonator Peter Braunstein. Braunstein, whose slurred cadence is due to the "don't be crazy" medicine they've put him on, describes the evening he held a former co-worker hostage and sexually tormented her for hours, as well as his hopes and dreams. It's a bizarre performance: The guy is clearly off the reservation, but how far off? He was polite enough to leave a thank you note at the scene of the crime, after all.
