Provocateur Sacha Baron Cohen confronted former GOP Senate candidate Roy Moore with a “pedophile detecting machine” on the latest episode of his Showtime program “Who Is America?”

Moore, who was accused during his campaign of sexually harassing multiple women when they were in their teens during the 1970s, sat down for an interview with Cohen, who was posing as Israeli anti-terrorism expert Col. Erran Morad, and the two began discussing technological advancements to thwart terrorist attacks.

Playing off that angle, Cohen says Israel developed a new piece of technology that can identify pedophiles.

“Sex offenders and particularly pedophiles secrete an enzyme for DDHT, which is actually detectable,” Cohen says. “It is three times the level as non-perverts, so the phrase ‘sweating like a rapist’ is actually based on science.”

He says the technology is used in schools and playgrounds to detect pedophiles by swiping a wand that beeps when the enzyme is detected on a person.

Holding the wand, Cohen says that “because neither of us are sex offenders,” it will make no noise. It remains silent as he moves it over himself.

Turning to Moore, Cohen waves the wand, which emits a beeping sound.

“It must be faulty. It’s malfunctioning,” Cohen says, then tries it several more times on himself.

As Moore sits there, Cohen says, “Is this your jacket? Did you lend the jacket to somebody else?”

“I’ve been married for 33 years, I’ve never had an accusation of such things,” Moore says. “If this is an instrument, then certainly I’m not a pedophile.”

“I am simply cutting this conversation right now,” he says and walks off.

Moore lost December’s special election in Alabama to Democrat Doug Jones, despite being endorsed in the deep red state by President Trump.

He isn’t the first politician punked by Cohen.

Georgia state Rep. Jason Spencer, a Republican, resigned last week after he dropped his pants and shouted racial slurs during an episode of Cohen’s show.
