  The Crab pulsar and plerion are some of the brightest and best studied
non-thermal astrophysical sources. The recent discovery of pulsed gamma-ray
emission above 100 gigaelectronvolts (GeV) from the Crab pulsar with VERITAS
(the Very Energetic Radiation Imaging Telescope Array System) challenges
commonly accepted pulsar emission models and puts the gamma-ray emission region
far out in the magnetosphere - close to or even beyond the light cylinder. We
present updated VERITAS results from the analysis of a data set that is twice
as large as the original data set published in 2011. The results are discussed
in the context of discriminating between different models put forward to
explain gamma-ray emission mechanisms and acceleration regions within the Crab
pulsar's magnetosphere.
