There's something about this, and cases like this, that just stinks. We all know it does, yet sometimes it's hard to put a finger on it. For me, the amorality of the lawyers just rubs me the wrong way. Someone says, "Mr. Lawyer, I'd like to sue X for Y, and I'll pay you handsomely for it." And the lawyer does, because it pays. It doesn't matter if the reason is bogus, it doesn't matter that X has to spend lots of money on a legal defense against something that has no merit. It only matters that the lawyer is being paid.
Of course, at this point, someone will probably pop off that I'm some sort of Commie or something. Nothing could be farther from the truth. Just because you CAN perform a service (regardless of whether you're being paid for it) doesn't mean you SHOULD. I have numerous skills, and I almost always expect to be compensated for my work, but there are some things that I simply will not build, for any price -- because I would consider it wrong to do so. It seems to me (and perhaps to a lot of people) that there is a dearth of lawyers who would say in the face of a paying potential customer, "No, I won't take your case. You're asking me to do something that's dishonest and immoral. Now get the hell out of my office."
There's a difference between working for money and working MERELY for money. In that sense I would term the latter type of lawyer as also a mercenary, and there seem to be entirely too many of them.
How do you deter a mercenary? I invite suggestions, but the only way I know of is through fear. With the collective intelligence of those on this forum, it shouldn't be hard to come up with some creative ideas on how to make a mercenary lawyer think twice about working MERELY for money.
