An icebreaker is a ship specially designed to force its way through ice-covered waters. Whether powered by gas turbines, diesel-electric power, or nuclear energy, icebreakers are expensive to build, very expensive to run, and uncomfortable to travel in on the open sea because they roll easily. Nevertheless, icebreakers are needed to keep trade routes open where there exist seasonal or permanent ice conditions. What three features must a ship possess in order to be considered an icebreaker?

Back in the day
When Jack "Machine Gun" McGurn, a member of Al Capone's gang, was almost killed by members of rival George "Bugs" Moran's gang, he devised a plan to retaliate: he would lure Bugs and his men into a warehouse and kill them. On the day of the massacre, Capone's men mistook one of Bugs's gangsters for the rival crime boss and opened fire. Bugs had not yet arrived at the warehouse and survived the attempt on his life. Why did bystanders who heard the gunfire allow the murderers to leave the scene?
