The Globe & Mail reports that the Canadian train plot was exposed by a tip from a Toronto imam:
A tip from a Toronto imam sparked an investigation that culminated in the arrests of two men who allegedly plotted to derail a Via passenger train.
The imam alerted authorities more than a year ago about a person he regarded as an extremist who was corrupting youth in his community.
That single tip led to what the RCMP on Monday called the first-ever Canadian bust of an alleged al-Qaeda terrorist plot.
