While information is sketchy, it seems that a number of shots were fired at people outside an Athens office of the Golden Dawn party. Two persons are dead, very probably GD members. The identity of the perpetrators is unclear. Police thinks it was a "terrorist act".
If indeed the perpetrators were members of a far left group, this goes to show that stupidity is not associated with a specific hue of the political spectrum. I hope they are arrested and tried and condemned. Presumption of innocence be damned.
