Whew! I was afraid that it was a random attack. A non-random attack is much less worrisome.
Not random attack....
All the local police and local news reporters try to achieve that status.
Otherwise it means all elderly people coming back from the store may get thrown to the ground and beaten, anyone on a subway platform could be pushed onto the tracks in front of a speeding train, all women joggers might get pulled into a van and raped and murdered and all families asleep at night may suffer getting home invaded and duct taped and tortured.
Better to say “believed to be a drug deal that went bad” or “thought to be revenge for rival gang member slashing their major dealer to death.” Then people feel safer.
