I think her wearing that pin was hypocritical and self-serving. I have no doubt that the elders in her congregation urged her to wear it as a "witness."
It's hypocritical because no JW in good standing can serve as an armed policeman. Accepting an honor for what her grandson did while at the same advertising her religion which disapproves of his doing so is two-faced at the very least.
I am very sorry the young man was killed, especially in the line of duty. But I have no respect for someone who would use the occasion of the President honoring his sacrifice to promote her own contrary beliefs and serve her New York GOD's (Guardians of Doctrine).
Have they no shame? No. They must promote the organization at all costs.
Something, something, something... and the horse they rode in on.
