Thomas Sowell uses the latest Herman Cain controversy as the basis for a new column on a broader issue:

Let’s start with the law. Some people may think the fact that the National Restaurant Association reportedly paid $45,000 to settle a claim made by one of its employees against Cain is incriminating.

Most of us are not going to part with $45,000 without some serious reason. But that is very different from the situation of an organization in the present legal climate.

The figure $45,000 struck a chord with me because, some years ago, my wife — who is an attorney — was fervently congratulated when her client had to pay “only” $45,000 in a jury award when the plaintiff was demanding $1 million, in a case that was as frivolous a lawsuit as you could find.

The person who was suing was a drunk driver, whose car went out of control and slammed into a tree. After the sheriff’s deputies arrested her, she sued them on dubious charges, and the sheriff’s department was glad it had to pay “only” $45,000.

The department was painfully aware of the uncertainty about what ruinous costs a jury might impose on the deputies.

The real scandal goes far beyond the case of Herman Cain and his accusers. The real scandal is that the law allows people to impose heavy costs on others at little or no cost to themselves. That is a perfect setting for legalized extortion.
