Copper prices have risen dramatically in the last year. Since then, there has been an increase in thefts from construction sites (mainly of copper pipes). Normally the thefts occur at night (when the sites are unoccupied), but one day some vandals approach a Bluth Company jobsite and attempt to load 3 bundles of copper pipes into the back of a van. Rather than let the thieves get away, Buster, a carpenter, chases them several miles in his car, before catching up to them and shooting each of them fatally with a nail gun. Please address the potential legal liability of the Bluth Company.
