I think
critical1 is right to be pretty suspicious of the Paris attacks.
my conclusion is that they were false flags.
What the main 'conspiracy' sites have not noticed though (although I emailed them) is how the Bataclan massacre was pulled off. Some of the Paris attacks might have been faked but the Bataclan was real and the eyewitness reports all genuine.
It's a ridiculously simple MO and highly disturbing.
And they used a very similar method for the Orlando shootings. The similarities between Orlando and the Bataclan are very pertinent.
