This is the second NYT article I see here today that is calling for more censorship because of some unsubstantiated claims. These people must be completely out of their minds.

And right below that, an IBT page repeating it verbatim without investigation:

It's not uncommon these days for news organisations to lazily use Twitter as a source in this way. Actually contacting the police force which had supposedly escorted voters would involve actual reporting.
Given no one has commented on why they down voted, this is just speculation on my part based on what I've seen elsewhere on HN.
