Ross Perot advocated door to door gun searches.
CSMonitor:
During a crime wave in Dallas in 1986, Perot set up round-table meetings between police officers and people in the news media. In those meetings, according to Todd Mason, former Dallas bureau chief for Business Week, in his 1990 biography of the businessman: Perot espoused cordoning off minority neighborhoods and searching door-to-door for weapons and narcotics.
I sat right next to him at one of those meetings. He didn’t mention that at the meeting I attended. If he had, he would have gotten an earful from me.
Was he prejudiced against minorities? In today's world he sure would be called racist.
