Kerry Howley of *Reason* has a [blessedly efficient article](http://www.reason.com/news/show/119180.html) summarizing the growth of the “[National Security Letter](https://www.cato.org/pub_display.php?pub_id=6699).” Her key point: bureaucratic error in the use of NSLs is an indictment of the NSL power, not a defense of its users.

Again, it’s brief, so [read the whole thing](http://www.reason.com/news/show/119180.html).
