" A year or so earlier I had been to the Sky River Rock Festival in rural Washington, where a dosen stone-broke freaks from Seattle Liberation Front had assembled a sound system that carried every small note of an acoustic guitar - even a cough or the sound of a boot drooping on the stage - to half-deaf acid victims huddled under bushes a half mile away.

But the best technicians available to the National DAs' convention in Vegas apparently couldn't handle it. Their sound system looked like something Ulysses S. Grant might have triggered up to addres his troops during the Siege of Vicksburg. The voices from up front crackled with a fuzzy, high-pitched urgency, and the delay was just enough to keep the words disconcertingly out of phaze with the speaker's gestures.
