his name is ted kaczynski. >> he was extremely smart, but socially awkward. in retrospect, we would have to consider a diagnosis such as asperger's syndrome where he had a hard time reading clues of other people's emotions. >> theodore kaczynski was born on may 22, 1942, to a working class family in chicago, illinois. the older of two brothers, he excelled academically. in the fifth grade tests showed his iq was 167, genius level. >> as he was so smart, he skipped two grades which then made him even more socially awkward, because now he was with students two years older than him. >> in high school the shy, young genius set his sights on the best. harvard university. >> he was only 16 when he went to harvard. he came from a very modest background. and in harvard, that's a snobby kind of environment. and he was also socially maladjusted so it was a disaster for him. >> at harvard, kaczynski was one of 22 student volunteers, chose on the take part in a study in a technology study of gifted undergraduates. what the participants didn't know was the test was alleged

ted kaczynski, it seems, had his own agenda and his own timetable. >> when the oklahoma city bombing was happening, theodore kaczynski was already on a bus on his way to deliver the package for sending to his next victim. >> on april 24th, just five days after oklahoma city, a mail bomb killed gilbert murray. president of the california forestry association. a timber industry lobbying group. in an earlier incarnation they had been targeted by radical environmentalists. >> the bomb that was sent to the forestry association was actually sent to his predecessor, a man named william denison. but he had retired and mr. murray had replaced him. the unabomber was proud of himself. it didn't matter that his bomb had killed the wrong man. they were engaged in the same kind of work, which was anti-environment in his opinion. and so it was okay. >> i'd been to a number of bomb scenes over my career, and the last one in sacramento was probably one of the more horrific. the shrapnel is usually what maims or kills the victim. most of the cases, nails, staples, and screws were used. that's an antipe

you write ted kaczynski, jeffrey dahmer, dennis raider, though each of these striking again and again and cities across the states, you talk about an element of fascination rather than fear. >> i look at the statistics very, very careful to see if it's true and frankly it's not. as a white person, for example, i'm six times more likely to be victimized by a white person. george zimmerman was more likely to be hit by lightning when he got out of his car that night in florida than hit by trayvon martin. >> i think we need to be showing african-american youth in more positive light and switching the fascination with the serial killers you talked about, for example, and we should fear them a little more. >> what's scarier than a murderer and rapist on the loose. i think that's a pretty scary thing. i think ultimately i have a belief when people are confronted by the facts and i have all the information in the book that they will change their point of view. the good news is most people don't want to be racist, we do want to be egalitarian. i'm trying to appeal to that part in all of us. >>
