The government didn't read him his Miranda rights because they have enough to convict him at trial already.

There were exigent circumstances to find out immediately if he had any other accomplices. Interestingly, the Canadians made arrests today of "alleged" terrorists;

Quote:

Alleged 'al-Qaeda-supported' plot against Via train thwarted Police say 2 accused were getting 'direction and guidance' from al-Qaeda elements in Iran There was a specific route targeted, not necessarily a specific train, Strachan said, although she declined to reveal the route. According to a Reuters report, U.S. law enforcement and national security sources said the alleged plot targeted a rail line between Toronto and New York City. The two men arrested are not Canadian citizens but were in the country legally, police said Monday. Investigators would not provide any details about their nationalities. http://www.cbc.ca/news/politics/stor...c-arrests.html

No connection from the reported arrests but this is a continuing thing. How many Canadians would have been on that train? "the alleged plot targeted a rail line between Toronto and New York City"
