In Europe, there are probably thousands of muslims, who are willing to commit the same murder as brothers Kouachi. They just don't have enough courage, or simply don't know where to buy a Kalashnikov.
There are probably hundreds thousands of those, who would not do it, but are happy someone else did.
World-wide, those numbers may go to millions.
There are around 10 muslim countries, where Charlie-like journalists would be not assassinated, but sentenced to death by legal court.
Muslim fighters are fighting brutal and barbaric guerrilla wars in the vast region over Africa and Middle east.
And we are still pretending that islam is a religion of peace.
Have we really become completely insane ?
