Justin McShane is probably one of my favorite DUI attorneys, if one has such a thing.  This is probably because he holds no punches and he delivers what he knows.  Although his blogs are not necessarily the best for those that are trying to understand the basics, they are an excellent resource for those of us that are trying to stay on top of our game.

In one of his latest blogs, he has presented us with a list of some of his more informative blogs (listed below).
