(salut...) I'm french but not a Muslim and I feel exactly as you do!
The first officer that these terrorists took down was a Muslim. He was defending the store and the innocent people who happened to be caught in this mess and he died doing so. That, to me, is a true Muslim.
Not some coward that thinks blowing up a store is a good idea. That is a coward. There's no point in attributing him to a nationality or a religion.
