Left Decides Some Information Too Dangerous to Allow

Shall Not Be Questioned points to the Defense Distributed website no longer allowing access to Pennsylvania residents because downloading those CAM files could be used by criminals to make guns.  Now, 20 more states have joined, suing the federal government for deciding the First Amendment applies to machining codes.  Will they sue over access to other ideas? Somewhere the Cato Institute web site is spreading dangerous ideas. I look forward to seeing them shut down the Colonial Williamsburg videos on musket making.  The ACLU stood by NAMBLA some years ago, defending their right to publish advocacy material about having sex with little boys.
