Todd Rosenblum: The speed of movement from ideation to action. We do not know how long these three killers discussed the attack, and whether they received external, operational guidance. But much like school shootings increasing the probability of more school shootings, it is possible Manchester inspired the London killers.
The London attack was not complex; it was killers acting out a sick fantasy. My hope is that the London Muslim community speaks out against the killers invoking Islam to justify their violence, just as the Manchester Muslim community did, and as we expect the Caucasian community to condemn white nationalist violence.
