  We have investigated the differences in apparent opening angles between the
parsec-scale jets of the active galactic nuclei (AGN) detected by the Fermi
Large Area Telescope (LAT) during its first 24 months of operations and those
of non-LAT-detected AGN. We used 15.4 GHz VLBA observations of 215 sources from
the 2 cm VLBA MOJAVE program. The apparent opening angles were determined by
analyzing transverse jet profiles from the data in the image plane by using
stacked images constructed from all available MOJAVE epochs for a given source.
We confirm our earlier result based on the first three months of scientific
operations of the LAT. The apparent opening angles of \gamma-ray bright AGN are
preferentially larger than those of \gamma-ray weak sources, suggesting smaller
viewing angles to the \gamma-ray bright AGN. Intrinsic opening angles for BL
Lacs are wider than those in quasars.
