On January 29, 2017, a young man in Quebec entered a mosque and fired his rifle into the crowd, killing six worshippers. On the same weekend, tens of thousands gather across North America to protest what they see as President Trump's discriminatory bans on Muslim immigrants and refugees. Do these events point to a more fearful future? Do they suggest more dangerous and precarious times ahead for Muslims in North America? The Fifth Estate searches for answers in Canada and the U.S. Mark Kelley is in Quebec City, to tell the story on the mosque shooting that has shocked a nation. Gillian Findlay reports from Boston, where everyone from the mayor and civil liberties lawyers to ordinary citizens are mobilizing to fight Trump's new restrictions.
