Not going to comment too much on the vest...lot of stuff there but maybe it's got to serve many roles. Colour seems appropriate to the surroundings. Who knows what his job within the department is?
The AR setup is pretty reasonable. Short AR, Aimpoint Micro is nice and light, light on the thing for target ID, KX3 will hopefully tame the short AR down a little for the guys next to him.
Bottom line from my perspective...he's doing a lot more worthwhile stuff with his guns and gear than I am. I don't feel I have the right to criticize his choices, at least not without knowing his obligations and requirements.
