I may be mistaken here, but I think people used to consider boomslangs to not be as dangerous as we consider them now. For this reason lots of people used to free-handle these snakes. I know keepers now that still bare-hand hold boomslangs. Not recommending it by any means, as I've seen the fangs of these guys and know that they are more than formidable. However, many boomslangs (including my trio) have a very placid demeanor, except at feedings. Only one I've ever kept would ever inflate herself and strike, and that quit very quickly as she learned I was harmless to her (these are very smart snakes I believe, and learn quickly).
