A Florida man has been charged with plotting to plant bombs in at least 10 Target Corp stores and then profit when the blasts caused the company's stock price to fall, federal prosecutors have said. Charles Barnett, 48, of Ocala, had asked a law enforcement informant to put the homemade bombs on the shelves of Target stores from Florida to New York state, the U.S. Attorney's Office for the Middle District of Florida said in a statement. "Barnett theorized that the company's stock value would plunge after the explosions, allowing him to cheaply acquire shares of Target stock before an eventual rebound in prices," the statement said.
