It isn’t as if it is hard to find such a link, but U.S. authorities under Obama are so determinedly clueless that it takes them a great deal of effort to arrive at the obvious. At very least, the shooter appears to have pledged allegiance to the Islamic State (Amirul Mu’mineen is Leader of the Believers, i.e., the caliph, and bay’ah is allegiance). Whether it was orchestrated from there or not doesn’t shed much more light on what happened, but since officials are forbidden to study or understand the jihadis’ motivating ideology, they make a great deal out of such matters, however little they warrant such treatment.
“U.S. probes possible international terrorism link with Texas shootings,” Reuters, May 4, 2015:
(Reuters) – U.S. authorities are investigating possible links between gunmen shot dead by police at an anti-Muslim event near Dallas and international terrorist groups, a U.S. government source said on Monday.
The source said the FBI and other U.S. agencies believed the incident on Sunday could have been instigated or directed by foreign-based militants such as Islamic State, which operates mainly in Syria and parts of Iraq.
