It is shown through multidimensional particle-in-cell simulation that the transverse instability of plasma electron holes is caused not by the previously proposed focusing of trapped particles, but instead by kinematic jetting of marginally passing electrons. The mechanism is explained and heuristic analytic estimates obtained which agree with the growth rates and transverse wave-numbers observed in the simulations.
