I've been following this story with great interest because I'm a boring person with nothing better to do.
But I am now wondering several things
A. How can the police rule out terrorism when they don't know who is behind it. Im not saying it is But seems odd how you would rule out something without knowing who the perpertator is.
B. Why the couple who were arrested and named were so from only a tipoff.
C. Given the police are now offering a reward, does that mean they are unable to identify the perpetrators.
This whole thing is really strange.
