Activity Overview

In "Brutus," Charlie is trying to trace the sale of a "straw gun." A straw gun is a gun that is purchased legally from a gun shop, transferred to a black market dealer, and then sold illegally. In order to find straw guns, Charlie creates a network that consists of all the people involved in the sale and purchase of the straw guns. He explains that this is similar to a telephone network.
Students will create a telephone network and calculate the value of the network.
