Five people have been killed and two children wounded after a man wearing a bullet-proof vest opened fire in the US city of Philadelphia. The suspected attacker, a 40-year-old man who is now in custody, was carrying an AR-15-style rifle, a handgun, a police scanner and ammunition. He has no known connection to the victims and, with no clear motive, the shooting appeared to be random.
Edited my reply to reflect that. My point is that “random” and “no motive” are compatible, “terrorism” and “no motive” are not. And random does not mean terrorism.
