The use of such technological advances as the polygraph would reduce the back load of court cases because innocence could be established early in the proceedings, Bailey said.
After the lecture, a student asked Bailey whether he was disturbed by the acquittal of clients whom he felt were guilty.
Bailey said that he was more upset about innocent defendants who were convicted because for every three guilty persons acquitted, 20 innocent people are convicted.
"Besides, those that are guilty and are acquitted are punished in other ways and I hope in part by my fee," he added.
Another student asked him for his opinion about Harry Reems' conviction for acting in a pornographic film.
"The Harry Reems conviction was a mistake because any arbitrary constraint on freedom of speech is the first indication of tyranny," Bailey said.
Bailey ended the evening by stressing the need for honesty in the law profession because lawyers "walk the edge of temptation."
