Earlier quoted context omitted.
Just causing terror doesn't make it terrorism. Causing terror as a means to further some political (or religious) goal would make it terrorism.
Money is pure politics. The attacker becoming rich can legally be considered a political goal as the nature of money is political. If they endanger an entity or someone else’s resources to gain that political goal they are guilty of terrorism as they used fear to enact political change.
That only true when right is up and down is left.
