Laws and case-law are always changing, but whatever lawyers do to stay current seems to work well enough.<p>Building codes change, but certifications for electricians&#x2F;plumbers&#x2F;whatever seem to work well enough.<p>The certifications I&#x27;ve heard of all come with an expiration date. The professional organizations I&#x27;ve heard of all require at least a little bit of ongoing study from their members.<p>I don&#x27;t see why what works well enough everywhere else wouldn&#x27;t work well enough here?
