Paul Krugman writes: Florida’s now-infamous Stand Your Ground law, which lets you shoot someone you consider threatening without facing arrest, let alone prosecution, sounds crazy — and it is. And it’s tempting to dismiss this law as the work of ignorant yahoos. But similar laws have been pushed across the nation, not by ignorant yahoos but by big corporations.

Specifically, language virtually identical to Florida’s law is featured in a template supplied to legislators in other states by the American Legislative Exchange Council, a corporate-backed organization that has managed to keep a low profile even as it exerts vast influence (only recently, thanks to yeoman work by the Center for Media and Democracy, has a clear picture of ALEC’s activities emerged). And if there is any silver lining to Trayvon Martin’s killing, it is that it might finally place a spotlight on what ALEC is doing to our society — and our democracy.

What is ALEC? Despite claims that it’s nonpartisan, it’s very much a movement-conservative organization, funded by the usual suspects: the Kochs, Exxon Mobil, and so on. Unlike other such groups, however, it doesn’t just influence laws, it literally writes them, supplying fully drafted bills to state legislators. In Virginia, for example, more than 50 ALEC-written bills have been introduced, many almost word for word. And these bills often become law.
