As a lawyer, your client's case must be handled as competently as you possibly can, regardless of what is going on in the world at the time. Allowing world events to distract and prevent you from providing the best possible legal representation you can is not acceptable. Imagine a client who is wrongly convicted of a crime, for example, because you allowed world events to distract you from presenting a compelling closing argument at trial.

Writing an addendum to justify a poor November LSAT score is unwise. If I were the admissions director, I would consider such a statement to be an indication of an extreme weakness in a candidate, rather than a valid excuse for a low score.
