When the Germany car massacre happened, it sure reconfirmed my belief that Islamist terrorism is a growing issue, one we need to be mindful with in our immigration policies. But was it true? My only source was Twitter. So, I decided to just hold comment until the Times or WSJ reported it out. And now we see his motives are fairly unclear. Which saves me having to retract anything. If you're a large account, you will never regret waiting for reliable sourcing before Tweeting.
