Later I took ethics from him and I can still remember him telling us that lawyers can get away with all kinds of horrible things - lying, sleeping with the clients - but for goshsakes don't EVER commingle the clients' funds into your bank account, even innocently, even if you don't take any, because they WILL disbar you for that. Not that he was recommending lying or sleeping with clients either, of course, although he did point out that Georgetown was among the first schools to require legal ethics and John Dean got an A in it and look what happened to him. (Yeah, a lecture tour, last I looked :P)
One of his obits said he was lecturing the hospital orderlies on how awful the Patriot Act was as they wheeled him down the hall. I hope I go out half as cool as that.
