Gas properties are derived using emission line diagnostics. The sources observed display narrow line emission at large distances from the radio axis, with a surprisingly rich variety of gas kinematics and ionization mechanisms (AGN photoionization, shocks, young stars), and present evidence for both jet-cloud interactions as well as possible tidal interactions. I discuss these results in the context of the nature/origin of the emitting material, and also the triggering of AGN in general.
