Truck crashes into British embassy in Tehran. This version from ABC News is by far the most "negative" version, quoting an eyewitness saying it looked like a suicide attack. But if you hav e seen how contraflow bus lanes work in Tehran it's hard to see how it could have been an accident. It's particularly bad timing too. The police drove off all the witnesses and this is not the way to dispel suspicion and establish trust. In open societies the truth is easier to establish, allowing for self-criticism.
