From the Kansas City Star:

Authorities in Wichita and some other cities across the country are investigating vandalism against Democratic offices, apparently in response to health care reform.

And on Monday, a former Alabama militia leader took credit for instigating the actions.

Mike Vanderboegh of Pinson, Ala., former leader of the Alabama Constitutional Militia, put out a call on Friday for modern “Sons of Liberty” to break the windows of Democratic Party offices nationwide in opposition to health care reform. Since then, vandals have struck several offices, including the Sedgwick County Democratic Party headquarters in Wichita.

...

Vanderboegh posted the call for action Friday on his blog, “Sipsey Street Irregulars.” Referring to the health care reform bill as “Nancy Pelosi's Intolerable Act,” he told followers to send a message to Democrats.

“We can break their windows,” he said. “Break them NOW. And if we do a proper job, if we break the windows of hundreds, thousands, of Democrat party headquarters across this country, we might just wake up enough of them to make defending ourselves at the muzzle of a rifle unnecessary.”
