“The location of this attack was no accident,” Ms. May said, adding that the terrorist chose to strike at the heart of the country’s symbol of democracy and freedom.

And it just happened to be where the decision was made to keep troops in the Middle East, killing Muslims.  The same decision was made in Canada, namely strike back at the source of the decision to attack Muslim countries. 

I can imagine the frustrations of those who had co-religionists being attacked. I know I was disappointed when Canada joined the worlds bully in attacking Afghanistan, I thought it was appalling. And I had no connection with them other than that they were humans. 

What does Canada have to do to have Canadians rebel against its politicians! Few seem to realize that if a  country has been abusing other countries for, in Britain's case for more than a century, that there will be blow back! 

So I believe that democracy and freedom had nothing to do with the attack in London. It was retaliation.
