CHEYENNE, Wyo. (AP) â€” An Australian man standing trial on a charge of robbing a Wyoming bankon New Year's Eve told jurors in an emotional opening statement Tuesday that he was justified because he gave much of the money to the homeless.Corey Donaldson, 39, is acting as his own attorney in the trial in federal court in Cheyenne. The burly man choked up as he addressed jurors. "I must say, I feel like a frightened child," he said. Donaldson is accused of robbing a Jackson bank of $140,000 by claiming explosives were planted around the building. In court Tuesday, Donaldson said he was the second of 11 children and grew up in the country outside Melbourne, Australia, only to see his own father lose his home to bank foreclosure. He said he's now a legal resident in the United States. Donaldson said he became homeless late last year, coming face-to-face with people who were on the streets because of bank foreclosures. He said he became determined to put people ahead of the law. "I came up with the idea that since the banks had been bailed out, and the people had not, I was going to confiscate money from US Bank in Jackson and redistribute it to the poor and homeless in America," Donaldson said. "And that's what I did." U.S. District Judge Alan B. Johnson ruled last week that Donaldson can't argue to the jury that he was justified in robbing the bank. The judge upheld repeated objections from the prosecution Tuesday as Donaldson mentioned he had given much of the money to homeless people. Jared Thomas Williams, branch manager of the Jackson bank, testified that Donaldson met with him in his office on the day of the robbery. He said Donaldson told him members of a Mexican cartel were outside the building, prepared to blow it up if Williams didn't turn over $2 million in cash. "There were four military-grade explosives that had been buried in the snow, and they were prepared to detonate them," Williams said Donaldson told him. Williams said he loaded $140,000, nearly all the cash in the bank, into a duffel bag and gave it to Donaldson.
