  We present a Boltzmann equation analysis of the transport properties of a
model of electrons with a lifetime which is short everywhere except near the
Brillouin zone diagonals. The anomalous lifetime is directly implied by
photoemission and c-axis transport data. We find quantitative agreement between
calculations and ac and dc longitudinal and Hall resistivity, but the predicted
longitudinal magnetoresistance disagrees with experiment. A possible
microscopic origin of the anomalous lifetime is discussed
