The point is to kill someone who might be about to disclose something you don't want disclosed, and create a chilling effect preventing others who might consider disclosing, whistleblowing, leaking, or simply reporting such things from doing so for fear they too would be murdered.

In this case, it's killing 1,000 (or more) journalists with one rigged car.
