Carol Rose, the executive director of the ACLU of Massachusetts, joined Boston Public Radio to explain the union’s opposition to a so-called “no-buy" list to prevent people with mental illness from getting guns.

She called the proposed list “security theatre” and said it would “criminalize having mental illness.”

“None of [the recent mass shootings] would have been prevented by this no fly list,” she said. “It wouldn’t actually have kept anybody safe.”

Rose stressed that the ACLU supports gun control within the limits of the constitution, but called for more effective methods than the "no-buy" list.

“There is no correlation between those people who are on that list and the people who are committing these violent crimes in these mass shootings,” she said. “In fact, there’s a greater correlation between being a white man and being part of this mass shooting than there is between having mental illness.”
