can't speak for Mackay,
but my best guess is......crowded shopping centers, a day when we as a nation (well most of us, bow our heads and give thanks for our many blessings)
prime time for terrorist either of the foreign variety or deranged individuals to make a "statement"
that statement seems more and more often to be one of taking innocent lives.
death to scumbags
I'm praying for the good guys in this situation (yes that would be cops)
I will be surprised if this is the only one this weekend.
