this shooting reminds me of the other shootings...
The shooting in Connecticut reminds me about the shootings in Canada. If I recall, there have been at least two shootings in Toronto, Ontario, Canada.
There was a shooting down at a busy food court at the Toronto Eaton Centre (one of the city's tourist attractions) in Toronto, Ontario, Canada back in June 2012 in which one person died along with four others injured.
A month later (but still in Toronto), there was another shooting in a neighborhood in Scarborough (a place within the City of Toronto boundaries), in which 2 people were killed.
It also brought me memories about the Dawson College shooting in Montreal, Quebec, Canada in 2006 and the shooting down at the University of Montreal in 1989.
