Jonathan Schwartz said he once believed that purely legal considerations should always take precedence in such cases.

"I thought [law was above politics]coming out of law school, when I was thinking like a lawyer," he said. "But when you go to a place like Washington and deal with medicinal marijuana, thinking like a lawyer, it's a no-brainer. It's flat-out illegal."

But nonetheless, cases involving marijuana are never clear-cut, Edward Schwartz said.

"Law is of politics," he said. "Erosion of public support for a law, whether it remains on the books or not, forces us to re-evaluate it."

Simpson, though he said politicians must think like human beings, said he believes they should have knowledge of the law.

"I would think you would want lawyers passing the laws rather than people who know nothing about the law relying on staffers who know nothing about politics."

As far as public mistrust of lawmakers goes, Simpson said that it can only be fairly applied to 5-10 percent of Congressional delegates.

"There are at least 10 percent of people in America who are screwballs, lightweights and boobs," he joked. "These people need to be represented."
