If I may extrapolate not on this particular malfeasance, but on the principle in general, a shohet, or Jewish butcher, is an important member of his community because if he does not fulfill his commitment properly, he brings other folks to fail to keep the commandments, even though unaware.

I've used this as a fundamental definition of what a professional is and does. A professional, be he or she butcher, banker, lawyer, engineer, doctor, etc. is someone who is paid to fulfill functions and obligations for the good of others, but who is not necessarily detectable in doing this duty properly except perhaps by other professionals. Therefore trust, honor, one's word, all have the same importance they ever had.

Character is ever the issue.
