While the rest of us ate brunch, slept late and took in the heat last weekend, someone in the San Francisco U.S. Attorney’s Office was apparently working overtime to turn a minor gun-case snafu into a bitter controversy that’s sent the federal defense bar into a collective conniption.

The problem began earlier this month, when Assistant U.S. Attorney Susan Jerich disclosed that over the course of listening to tapes of jailhouse phone calls made by Lloyd Jamison — accused of being a felon in illegal possession of a gun — she accidentally listened to part of a conversation between Jamison and his lawyer, Ian Loveseth.
