Has Anyone Seen Brian Kennan?

Consider this post from Davis Wright Tremaine’s Digital Media Law Blog, or this post from the firm’s Privacy and Security Law Blog.
Now, suppose a prospective client reads either post and decides to contact the author. He clicks the link to Brian Kennan, but, rather than Kennan’s contact info, the prospective client sees this:

OK. So Kennan left the firm, and the firm wants to make like he never worked there.
But Kennan did work there, and something he wrote has attracted a prospective client. Given what it’s done, does the firm have any chance of converting this client?
I say, the firm would have a better shot at converting this client if — rather than posting an error message — it displayed this page or this page instead.

I say, the firm should come up with a comprehensive policy on what to do with the dearly (or otherwise) departed, one that also handles things like this.
