Abstract	Jets in blazars and other active galaxies are an excellent forum for studying cosmic ray acceleration at relativistic magnetohydrodynamic shocks, since this process is likely to spawn the highly-variable emission seen across the electromagnetic spectrum from radio to gamma-rays. Recent work has combined multi-wavelength leptonic emission models with complete simulated distributions from shock acceleration theory, resulting in new insights into plasma conditions in blazar jets, likely to apply to radio galaxies as well. This has demonstrated the ability to infer the plasma density, and suggested the interpretation that turbulence levels decline with remoteness from jet shocks, with a significant role for non-gyroresonant diffusion. This talk reviews these insights and the status quo for shock acceleration scenarios for dissipation in extragalactic jets, and presents new results from a two-zone time-evolving construction, modeling together both extended, enhanced emission states from larger radiative regions, and prompt flare events in select Fermi-LAT and TeV blazars. The added constraints break parametric degeneracies in shock and plasma quantities, leading to refined determinations of the plasma density and particle diffusion character in blazar jets.
