The world is ruled by violence.
Bob Dylan
Indeed it is, even in democratic, "social contract" nations where the threat of state violence (police, jails, FBI, Federal prosecutors, etc) is a big part of what holds things together - supposedly. So it's funny to see "life in a bubble" folks at Harvard horrified when a dog kills a squirrel. Harvard Crimson. (h/t, Instapundit). There's a lesson in that.
