If you have the option to use different resumes to submit to different firms, I'd consider not including your criminal law club officer's position at all. It demonstrates an interest, which is ok for a firm that has a criminal practice (or if you can spin it into "i like securities fraud, etc, which mainstream firms may practice civilly). However, my impression is that officer positions have almost no weight unless you're president of a group (most organizations get very little real work out of their officers, but I digress). It's a good conversation starter if you need it but not a very effective selling point on why they should hire you.
another interesting topic for another day is when and what to start removing from your resume as it fills up with legal accomplishments, and what not to include at all (I personally don't see the point of putting "dean's list" on your resume if your GPA demonstrates good grades, for example).
This is true. In truth, officer positions are for those who couldn't do anything real. Do firms really respect the fact that you were on the SBA and helped plan the drinking parties all semester? Or that you helped distribute flyers to generate interest in the crim law club? The only point of clubs is to be around people with similar interests and maybe get some good discussion out of it.
I say leave it off your resume altogether.
