  Powerful winds with wide opening angles, likely driven by accretion disks
around black holes (BHs), are observed in the majority of active galactic
nuclei (AGN) and can play a crucial role in AGN and galaxy evolution. If
protons are accelerated in the wind near the BH via diffusive shock
acceleration, $pp$ and $p\gamma$ processes generate neutrinos as well as pair
cascade emission from the gamma-ray to radio bands. The TeV neutrinos detected
by IceCube from the obscured Seyfert galaxy NGC 1068 may arise from
collisionless shocks in a failed, line-driven wind that is physically well
motivated. Although the cascade emission is $\gamma\gamma$-attenuated above a
few MeV, it can still contribute significantly to the sub-GeV gamma rays and
the sub-millimeter emission observed from NGC 1068. At higher energies, gamma
rays can occur via $pp$ processes from a shock where an outgoing wind impacts
the obscuring torus, along with some observable GHz-band emission. Tests and
implications of this model are discussed. Neutrinos and gamma rays may offer
unique probes of AGN wind launching sites, particularly for objects obscured in
other forms of radiation.
