AUGUSTA, Maine — Legislation has been introduced in the U.S. House and Senate to require Facebook and other social media sites to block use of their platforms by groups selling weapons needed by terrorists.

In recent months, sites on Facebook have sought to sell everything from heavy machine guns to anti-aircraft missiles. Maine Sen. Angus King, who serves on the Senate Intelligence Committee, says requiring social media platforms to block those sites isn’t the right strategy.

“I don’t think it’s appropriate, or will be effective, to try to legislate what Facebook can have on its pages,” King says. “I think a much more effective way to handle this is to have Facebook itself, which I understand is its policy, to say we are not going to carry these kind of messages.”

King says, like other technologies, Facebook can be used for good purposes as well as bad. He says it’s important for government agencies to work with social media platforms to police themselves and not seek to regulate them.
