I've known many, many lawyers. Some are truly excellent, many are average, and a few are truly horrible. After all this time I know who I would go to for top notch representation in almost any kind of law you can think of. I also know who I hope the other side would end up with as their counsel.
Several lawyers I've known, one of them a truly gifted and respected attorney, ended up going to prison for stealing from their clients. Once I had an attorney, whose client I just testified against, stop me on the way out of court to ask me how to file a motion for their client. As they asked their client was looking at them with an expression that indicated they were thinking "I'm paying you $250 an hour to ask the cop what to do!". The attorney's defense was that they normally didn't do these cases, and they didn't want to ask the ADA for help.
As far as judges being armed, I've got lot's of good armed judges stories. One judge kept a pistol grip 870 on the bench. Another judge, while conducting a family court hearing, flipped out screaming at an attorney and started waiving a loaded revolver around. All that happened to that judge, after the incident made the paper, was to be asked not to do that again. Another judge declared a recess to ask me about getting a membership at my sportsman's club. One judge used to conduct firearms training for the other judges at his private range.
I will say that on balance I've known more really good lawyers and judges than really bad ones. I will also note that in my younger days I was lucky enough to work with some truly stunning female ADA's and PD's. I honestly looked forward to going to court back then.
