bill kurtis, the veteran anchor at the cbs station in chicago, is a windy city institution, and this week he spoke out about something both personal and painful, prompted by the media furor surrounding jared loughner and the shootings in tucson. >> my son was schizophrenic. and i've been listening of course over the weekend and trying to draw parallels. one, he showed a dramatic personality change at 19. i was told by doctors that at 19 something happens in the brain to turn off a chemical perhaps. i was told my son went non-violent and he was no danger but 10% of the crimes are committed by mentally ill people who do turn violent. >> kurtis's son scott died a year and a half ago at the age of 38. the wbbm anchor joins me now from chicago. bill kurtis, welcome. >> good morning, howard.
