Generally not. Although all lawyers are trained to research and understand the law, a lot of fighting a criminal case depends on understanding how the system works and where to find all of the relevant laws. With the way the laws are written, the punishments and license suspensions aren't published in the same statute as the crime itself. While a lawyer with no or a little but of experience can certainly do the research to find all of the relevant laws, an experienced criminal attorney will already know the law and where to look for updates.
