so because God never stopped the shooting he allowed it ?
Yep this is where your knowledge of certain things is all over the place.
More than likely rufus the shooter would have had some condemning thoughts not to go through with the shooting but he chose not to.
The reality of that is God did not allow it. Romans 2:15
All deeds are seen in the light all consciences get pricked God is everywhere.
God being omniscient can either mean he predetermines everything or he knows everything that is going to happen.
I go with he knows everything.
Which means that you too, like Genez, reject the truths taught in Ps 146:9; Job 5:12-13; 2Thes 2:7. See how much you really have in common with Genez. Pretty soon I'll have both of you joined at the hip!
And, yes, God allowed two people to be killed because everyone's life is in God's hands. God alone numbers everyone's days (Dan 5:23). But at the same time, God preserved Trump's life since the number of his days did not expire at that time. God, evidently, wanted to raise up Trump as the ruler of this nation.
