3 people were murdered & the murderer was shot in self defence!
Unfortunately, this is becoming the new "normal".
Just the location changes.:(
I lived in London for a few years.
There have always been terrorist attacks there from one group or another. Its part of living in London its not a 'new normal'. It's been there for a long time.
And sadly it seems that we are becoming desensitised too. However, watching the footage captured on phones yesterday I could feel the terror those poor people faced.
