Pity the poor company that ends up in someone’s portfolio in a blind trust. Through no fault of its own, a Chinese company called Uniview Technologies Co. was dragged last week into the Mitt Romney family’s blind trust—and thus into U.S. election-year politics.

It happened last week when The New York Times ran a story saying a fund run by Bain Capital, the private equity company that made GOP presidential candidate Romney a multi-millionaire, bought the video surveillance unit of Uniview. The Chinese company claims to be the largest supplier to that country’s public monitoring system, which keeps an eye on universities, hospitals, mosques, and yes, Tibetan monks.
