Stories like this scare me.

One of my worst fears is that one day I'll wake up in a Paris bank waving a gun and smoking a cuban cigar.

Can any of us go to sleep knowing for certain that come morning we won't be in a federal prison, serving time for crimes we commited during our sleep?

Food for thought.
