  To study a statistical properties of different classes of radio sources, 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 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.
