The Wall Street Journal placed this shooting in the context of a series of ISIS-inspired lone wolf incidents in the United States, including the 2015 San Bernardino attack, pointing out that some 60 individuals were arrested in 2015 in the United States charged with giving support to ISIS; the "Journal" quoted Michael Nacht, a former official with the U.S. Defense Department, now a Professor at the University of California, Berkeley's Goldman School of Public Policy, who stated that calling on Muslims worldwide to attack non-Muslims is "a very effective ISIS strategy."
