Powerful winds with wide opening angles, likely driven by accretion disksaround black holes (BHs), are observed in the majority of active galacticnuclei (AGN) and can play a crucial role in AGN and galaxy evolution. Ifprotons are accelerated in the wind near the BH via diffusive shockacceleration, $p\gamma$ processes with AGN photons generate neutrinos as wellas pair cascade emission from the gamma-ray to radio bands. The TeV neutrinosdetected by IceCube from the obscured Seyfert galaxy NGC 1068 can beinterpreted consistently if the shock velocity is appreciably lower than thelocal escape velocity, which may correspond to a failed, line-driven wind thatis physically well motivated. Although the $p\gamma$-induced cascade is$\gamma\gamma$-attenuated above a few MeV, it can still contributesignificantly to the sub-GeV gamma rays observed from NGC 1068. At higherenergies, gamma rays can arise via $pp$ processes from a shock where anoutgoing wind impacts the obscuring torus, along with some observable radioemission. Tests and implications of this model are discussed. Neutrinos andgamma rays may offer unique probes of AGN wind launching sites, particularlyfor objects obscured in other forms of radiation.
