  The statistical analysis of parsec scale region of radio galaxies is crucial
to obtain information on the nature of their central engine. To this purpose,
we defined and observed the Bologna Complete Sample (BCS) which is unbiased
with respect to the orientation of the nuclear relativistic jet being selected
from low-frequency samples. The BCS is a complete sample of 94 nearby (z<0.1)
radio galaxies that are well studied targets with literature kiloparsec data.
For all of them, we collected parsec scale information asking new VLBI (VLBA
and EVN) observations. Statistical results on their properties in radio band
are presented. From the estimates of the Doppler factor and viewing angles, we
discuss the connection with the available gamma-ray data. Finally, we show how
future observations with Fermi could reveal new important detections of some of
the BCS sources.
