Jim Harper sifts through the evidence in the “Destroy America” Twitter case:
The Department of Homeland Security has been vague as yet about what actually happened. It may have been some kind of “social media analysis” like this that turned up “suspicious” Tweets leading to the exclusion, though the betting is running toward a suspicious-activity tipline. (What “turned up” the Tweets doesn’t affect my analysis here.) The boastful young Britons Tweeted about going to “destroy America” on the trip — destroy alcoholic beverages in America was almost certainly the import of that line — and dig up the grave of Marilyn Monroe.
Profoundly stilted literalism took this to be threatening language. And a failure of even brief investigation prevented DHS officials from discovering the absurdity of that literalism. It would be impossible to “dig up” Marilyn Monroe’s body, which is in a crypt at Westwood Memorial Park in Los Angeles.

Other facts could combine with Twitter commentary to create a suspicious circumstance on extremely rare occasions, but for proper suspicion to arise, the Tweet or Tweets and all other facts must be consistent with criminal planning and inconsistent with lawful behavior. No information so far available suggests that the DHS did anything other than take Tweets literally in the face of plausible explanations by their authors that they were using hyperbole and irony. This is simple investigative incompetence.
If indeed it is a “social media analysis” program that produced this incident, the U.S. government is paying money to cause U.S. government officials to waste their time on making the United States an unattractive place to visit. That’s a cost-trifecta in the face of essentially zero prospect for any security benefit.
