Can anyone elaborate on what this paragraph is trying to say?
I want to know how Acceturo and Tacetta fit into Bruno murder?
How did they exploit?

It was on Wiki: (I know wiki is bad for facts but they are right most of the time I think)

Here is post:
On March 12, 1980, the boss of the Philadelphia crime family Angelo "Gentle Don" Bruno was shot to death, in the aftermath of which the double dealing Funzi Tieri of the Genovese LCN had "The Commission" support the murder of all those involved in the Bruno murder (though they had been encouraged to do the same by Tieri). After this, Philip Testa found himself boss, but was killed by his underboss Pete Casella. Consigliere Nicodemo Scarfo, then fighting the remnants of the Casella faction to maintain control of the Philadelphia family. When Accetturo heard of this, he ordered Taccetta to establish a new crew of the Lucchese crime family, under Taccetta's control. Because of the bad relations between the two factions in Philadelphia's crime family, and Taccetta and Accetturo exploiting the situation, the relationship between Philadelphia and the Five Families worsened.
