What Happened In Quebec?

Several reports have surfaced that contradict the official version that has been disseminated over the past 18 hours.

There have been no clear answers to early reports suggesting that:

a) there were two hooded attackers shooting
b) the assailants shouted Allahu Akbar
c) the two suspects were held overnight and then one released as a "witness"

Something seems off and has the smell of a false flag in my view.
