Raymond Johnson snatched a purse that had been left in an unattended car at a gas station. The purse contained both money and a firearm. Johnson was convicted for the crimes of grand theft of property (cash and payroll check) and grand theft of a firearm. Johnson appealed, arguing that this conviction is a double jeopardy violation in that it constitutes multiple convictions for a single act. Should he be convicted of two separate crimes for stealing the purse?
