I will discuss possible origins of the HE and VHE emissions observed in low luminosity AGNs, focusing on magnetospheric emission. Recent work suggests that local discharges in polar gaps in rotating black holes may account for the variable TeV emission detected in M87 and, conceivably, other sources. It has also been suggested that the plasma produced in the spark gap may be dense enough to account for the radio emission seen on horizon scales in M87. I will discuss the processes that control the gap structure, and elucidate the conditions anticipated in deferent sources.
