A random killer randomly shot and killed one person each at an event celebrating free speech attended by a cartoonist who portrayed Mohammed as a dog, and at a synagogue in Copenhagen. Other 21st Century random shootings and random bombings of random folks by other random folks for totally random reasons at totally random locations. (Source)

This list does not include random beatings, random rapes, and random vandalism of random folks, random homes and random businesses by other random folks randomly yelling "Allah Akbar."

I wonder if there is anything these have in common?
