“The shooter was just another hateful, lost young man who grabbed onto radical ideas wherever he could find. He did not have a coherent worldview other than hate and resentment.”
His grandfather, whom he looked up to, was a radical Iranian Islamicist but nothing to see there according to you.
- The shooter never mentioned islam, Mohammed, Jihad, etc.
- So far there is no indication that he attended a mosque.
- No mention of him yelling "Allah Ackbar".
There is just the datapoint of a picture of a grandfather or great grandfather. That's thin.
Let's wait until more info comes out about his background, friends, etc.
