Gutmacher said that he tells his clients to ask as many questions as possible about a customer's mental health, including whether they are currently taking anti-depressants or anti-anxiety medications as well as whether they have had any suicidal thoughts in the past two years.
But even Gutmacher said that his own advice is unlikely to stop suicidal customers from renting guns.
"As long as you're not a convicted felon you can go into a gun range and rent a gun," said Gutmacher.
"If someone wants to commit suicide he's going to lie. Those questions aren't going to stop them," he said.
Harvey said that at his own range, he and his employees always ask about a customer's mental state, even though "they don't have to."
We can't even do a background check unless they're purchasing. You can't do a real mental check," said Harvey. "That's frustrating."
Asked whether he has ever turned prospective gun renters away, Harvey said that he has, but it's the rare exception.
"Ninety-nine percent of the time we don't have to," he said. "Occasionally there is someone who just seems a little strange."
"I guess my employees need to be psychiatrists soon too," said Harvey.
