Thomas Jefferson gave religious freedom generous limits. He included foreign religions such as Hinduism and  Mohammedanism. The thing is, these kind of attacks aren't religiously inspired. They are just a symptom of the times. Too many different people's friction created this. Those losers can't fit in, so they seek fame and fortune by engaging in acts so evil that no religion on earth would ever have endorsed, nor could they condone murdering innocent people gratuitously.   
The lady from Calgary killed by those losers was a good person that didn't do any harm to anyone. She was killed for being somewhere that an evil group of losers targeted for their quest for fame. 
These killers shouldn't be glorified by showing their photos all over the world. These kind of evildoers should never be known, their names should never be advertised and their fame shouldn't be spread by media. They aren't worth advertising to potential copy cats. There are too many marginalized foreigners angry at us.
