Thomas Shaw, the Episcopal Bishop of Massachusetts, just returned from a secret, week-long trip to Zimbabwe. While there, he witnessed the economic strife that has left the country with soaring inflation and sky high energy and food costs. Bishop Shaw comments on the violence unleashed by President Robert Mugabe against the opposition party in the run-up to the June 27th run-off election with Morgan Tsvangirai. The Bishop also says Anglicans are being targeted, with church property stolen and parishioners prevented from holding church services.

Our guest is Laurie Lane, president of ReRun, a New Jersey based racehorse rescue group.
