Linear polarization that is generated close to the black hole in LLAGN must propagate through a dense, magnetized accretion flow. The observed Faraday rotation is a strong constraint on the integrated accretion flow properties as has been demonstrated on Sgr A*, M87, 3C 84, and other sources. We have also recently shown that several LLAGN follow a damped random walk (DRW) light curve. The saturation time scale of the DRW is comparable to the orbital period at a few Schwarzschild radii for these systems. Together, polarimetric and temporal probes provide important constraints for high angular resolution observations of these systems that will enable us to convincingly extract fundamental accretion, outflow, and general relativistic physics.
