The question, as posed in your subject line is pretty specific. However, the body of the post opens it up to "high fence" deer, which is not illegal. As another said: "Legal" meaning within state game laws? I'd bet a fairly large number were taken with what would be considered "aid of bait" or not within legal shooting hours. If you factor in all the other nitpicky things that might make a hunter technically "not legal" ie: without proper orange etc. then a great number. Truely poached deer? Far less, but a few. High fence deer? Who knows, and who cares?
