When I heard there was more than one. Multi-shooter attacks are very rare. The last one that wasn't terror was Columbine.
To anyone who thinks that something like this is related to Islaam, I say that Islaam forbids terrorism in the Qur’aan (2: 62 – 256) (3: 3 – 199) (4: 3 – 162) (5: 33 – 108) (7: 157 – 170) (8: 7 – 73) (9: 2 – 128) (16: 61 – 128) (33: 9 – 73) (47: 2 – 38) (58: 5 – 13) (65: 4 – 6), like in 4: 89 – 90: “They but wish that ye should reject Faith, as they do, and thus be on the same footing (as they): But take not friends from their ranks until they flee in the way of Allaah. But if they turn renegades, seize them and slay them wherever ye find them; and do not take a friend or helper from their ranks. EXCEPT those who join a group between whom and you there is a treaty (of peace), or those who approach you with hearts restraining them from fighting you as well as fighting their own people.
If Allaah had pleased, He could have given them power over you, and they would have fought you: Therefore if they withdraw from you but fight you not, and (instead) send you peace, then Allaah hath opened no way for you against them.” In other words, Verses of fighting or killing, like 4:89, referred to people at war with Mu? Ammad, not necessarily non-Muslims who were not at war with him.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
