Scientists discover what they can (falliable as they may be).
Politicians take scientist's best understanding at the time, balance the concerns of various groups, and make a decision.
Politicians decisions are backed up with violence (always, not just for this) because states having a monoply on violence is just how states work.
Scientists discover what they can.
A healthy media informs the public so they can decide to act on this knowledge.
At the same time politicians find ways to help or subsidize desired behavior, and lend weight to the media message. Harmful behavior is prosecuted (the word you're looking for is "force"... not violence).
That's how it's supposed to work. It doesn't work that way anymore, but it's supposed to.
Yes its regrettable that the media seems to be mucking up its role as the fourth estate (or at least sowing division and acting in ways that seem less than beneficial to the well being of the group). However, that's hardly unique in history, and arguably one of the primary functions of a free press is to spread dissent in order to keep the power of the state in check.

Is there a difference? or is it "force" when it happens to other people, "violence" when it happens to you or you disagree with it?
