Republican presidential candidate Ben Carson on Tuesday suggested using "medical ways" — such as decreasing people's conscious defenses — to extract information from terror suspects.
"I believe there are a number of ways to extract information, including some medical ways of putting people into a less-than-conscious state, which allows information to be extracted," he said on CNN.
"There are ways where you decrease a person's conscious defenses, and they might be much more willing to give information," he said.
Carson added that there are a variety of different things that can be used for this purpose.
"We've made some advances in that kind of science," he said.
