Act of terror against 'free expression' in Paris

Salve,
January 7th should be a joyous day for today's day when the Eastern Orthodox Church celebrates Christmas (due to their use of Julian calendar), and yesterday the Western Christianity, especially the Catholics around the world celebrated the Feast of Epiphany. (also the Day of Trzech Króli [Three Kings] in Poland).

You know, when the Soviet Union collapsed I did expect a happier, better and peaceful New World...
ps
a look by Forbes at the media (AP, NYTimes et al) and Charlie Hebdo tragedy. 

obvious  question remains 'cui bono' - so  opinions (some extreme) away from the mainstream Western media: Cockburn, old Reaganite  Roberts, Ertem, by Spengler   and Escobar from Asia Times- (9 Jan 2015) - perhaps I will add more in time.
