“...the suspect was “an older white man,” who became radicalized after reading extremist Islamic material...”
The news media will be completely confounded on how to handle this.
“white man” is a natural magnet for the scathing sword of condemnation by the lame stream media.
But toss in Islam...and they have a problem. How can they talk trash about the guy without offending the mooslems? They will have to step gingerly.
Not at all. They'll just boil it down to something the low-information voter can understand: "Angry old white man".
