Well, walk up to a cop and call him a dickhead, and, depending on his mood, you're likely to be busted for public drunkeness or disturbing the peace or loitering or some nuisance charge. They'll haul you down to the station and toss you in the pokey for a few hours (to "calm down" or "dry out" or whatever), then let you go with no charges filed. However, none of that is technically legal--it's just impossible to prove the cop acted improperly unless the same officer has a history of this kind of thing. So yes, it's legal to insult a cop.
Same with a judge--actually, it's safer, because a judge doesn't carry handcuffs. You still have to be careful--you can't pull things like follow him to his car and shout at him or something--but just walking up to him on the street or in a restaurant and going, "Judge Smith, I just thought you'd like to know that I think you're a total dickhead," and then walking away, is legal.
Written insults are even safer, because in most cases, there's no way you can accuse someone who's, say, written something nasty about someone else in a blog, of being a thread to the safety of the individual in question. You have to be careful not to libel someone or make threats of violence, but the standards for both are pretty tight and it's hard to accidentily do it (imposible in the case of libel, since the libeled party must prove the writer was deliberately lying AND meant to ruin the libeled party's reputation).
Short answer: yes, in the states, you can insult anyone you feel like so long as you don't threaten or slander him. "Personal honor" means squat in the American legal code. Now for a fun exercise, how about one of the people here defending the German legal code show me how you can prove that by harming someone's personal honor, you've caused him real, objectively verifiable harm that justifies a one year prison term.
