First, let me apologize for not seeing this question until now. I see that you sent it to me a week ago (I've been busy.)
Lawyers have a bad reputation, in general, and are food for comedians due to several things:
First, most of the time that a lawyer is needed, there is an underlying conflict. Conflict lends itself to emotional responses, and for the party on the "losing" side, those responses are not usually going to be "good."
It's easy to blame a lawyer rather than the laws themselves or the facts of a case which lead to a lawyer's choices. MOST lawyers are good, and MOST follow the law. When someone "hates" a lawyer, it's often the law that he disagrees with, but the lawyer shoulders the blame.
Also, bad lawyers give the profession overall a bad name. And it seems like it is the bad lawyers who get the press, not those of us who dedicate so much time, energy, and money to helping the underprivileged, etc.
Lawyers are expensive. In some cases, it is not justified -- but in most cases, it is. We work HARD. And it takes us many years to even become an attorney. Having said that, if a client pays an attorney oodles of cash and then loses ... Well, who is going to be the object of criticism?
Lawyers have to work with the laws and the facts. When those two things don't support a winning cause, a client isn't going to be happy. But they can't really scream at a law book with much satisfaction. And they sure aren't going to blame themselves, such as when the facts the lawyer has to work with include things like a client lying to a cop, white-collar crimes, or unacceptable (but not illegal) behavior that a jury finds objectionable.
These things tend to make the lawyer the bad guy.
