That's where there was a failure to apply critical thinking...an unfortunately frequent side effect of these discussions.
Agreed on critical thinking, but how does that apply to conflicting news reports?
My guess is to wait for investigations to be completed and all facts revealed.
OTOH, given several events of Islamic terrorism on infidel Westerners, is it really that big a jump to think this is related to those events?
FWIW, I think Daesh and other Islamic terrorists rely upon the mentally defective and mentally ill (yes, there's a difference) to carry out these acts of mass murder and suicide.
Lastly, let's be straight. I don't condemn all the world's 1.6 BILLION Muslims for the acts of a few. OTOH, if those 1.6 Billion don't start actively fighting and stopping Islamic terrorism, they will be seen as complicit.
