Meanwhile, a Tennessee government official claimed that complaining about water quality could be considered an act of terrorism. To the government's credit, he was subsequently demoted for those remarks.
The notion of making a terrorist threat is older than the current spate of anti-terrorism craziness. It basically means threatening people in order to terrorize them, and can include things like pointing a fake gun at someone, threatening to set off a bomb, and so on. A Texas high-school student recently spent five months in jail for writing the following on Facebook: "I think I'ma shoot up a kindergarten. And watch the blood of the innocent rain down. And eat the beating heart of one of them." Last year, two Irish tourists were denied entry at the Los Angeles Airport because of some misunderstood tweets.
Another term that's expanded in meaning is "weapon of mass destruction." The law is surprisingly broad, and includes anything that explodes, leading political scientist and terrorism-fear skeptic John Mueller to comment:
As I understand it, not only is a grenade a weapon of mass destruction, but so is a maliciously-designed child's rocket even if it doesn't have a warhead. On the other hand, although a missile-propelled firecracker would be considered a weapon of mass destruction if its designers had wanted to think of it as a weapon, it would not be so considered if it had previously been designed for use as a weapon and then redesigned for pyrotechnic use or if it was surplus and had been sold, loaned, or given to you (under certain circumstances) by the secretary of the army ....
All artillery, and virtually every muzzle-loading military long arm for that matter, legally qualifies as a WMD. It does make the bombardment of Ft. Sumter all the more sinister. To say nothing of the revelation that The Star Spangled Banner is in fact an account of a WMD attack on American shores.
After the Boston Marathon bombings, one commentator described our use of the term this way: "What the United States means by terrorist violence is, in large part, 'public violence some weirdo had the gall to carry out using a weapon other than a gun.' ... Mass murderers who strike with guns (and who don't happen to be Muslim) are typically read as psychopaths disconnected from the larger political sphere." Sadly, there's a lot of truth to that.
Even as the definition of terrorism broadens, we have to ask how far we will extend that arbitrary line. Already, we're using these surveillance systems in other areas. A raft of secret court rulings has recently expanded the NSA's eavesdropping powers to include "people possibly involved in nuclear proliferation, espionage and cyberattacks." A "little-noticed provision" in a 2008 law expanded the definition of "foreign intelligence" to include "weapons of mass destruction," which, as we've just seen, is surprisingly broad.
