The target doesn't seem to fit the targets of classic islamic terrorism, hence why I said it doesn't appear to be political or religious in motivation. The target generally fits the disgruntled office employee situation more. And (at least so far) there doesn't seem to be any message or extremist affiliation, or history of extremism.
The prep work, religious affiliation, and travel history, though, fit islamic terrorism, and not disgruntled employee.
That's why it comes off as so weird to me, it's like a mix of both, and neither at the same time.
Either way, the couple in question are !@#$s, and I'm glad they're dead.
