"We are more casual about qualifying the people we allow to act as advocates in the courtroom than we are about licensing electricians"

This quote by Warren E. Burger is referring to the absence of certifications required to be an advocate in the courtroom. He is implying that the qualifications for being an advocate in the courtroom are much less strict than the credentials for being a certified electrician. This could be interpreted as a criticism of the legal system, as it suggests that the qualifications for being a supporter in the courtroom are not as strenuous as they must be. It might likewise be translated as a criticism of the electrical contractor licensing system, as it implies that the certifications for being a certified electrician are too stringent. Ultimately, this quote is a commentary on the differences in qualifications for various occupations.
