Suppose, as seems likely, Canadians respond to such events by tightening security around politicians, government institutions and such ceremonial events as Remembrance Day.

How do we imagine terrorists, radicalised persons, crazies... will respond to ensuing difficulties of getting at ' targets of choice'?

Will they stand down or rethink strategies against the possibility of  better opportunities?

Alternatively, since terrorists tend to be impatient to get on with God's work, will they start choosing less well-guarded infidels to execute or, ideally, behead?

Terrible stuff!  There is, however,  a tiny benefit.  If enhancing the security of important people and institutions deflects terrorists' attention to ordinary folk, then ordinary folk can test their  love for democracy  and elected representatives by considering  whether this increased risk is meet and proper.
