Wrong, it's very cheap to execute someone. A few hundred dollars' worth of chemicals, a twenty cent 9mm bullet or twenty dollars of reuseable rope. What make it expensive is all the appeals people like you launch to delay the execution of the sentence. Keeping someone in prison is incredibly expensive, it takes THIRTY-SIX THOUSAND dollars a year to keep a federal prisoner confined, a California prisoner costs ONE HUNDRED THIRTY-TWO THOUSAND EIGHT HUNDRED AND SIXTY dollars a year to keep confined.
