I suspect many remain silent as they fear the wrath of vengeance that will get dished out if they speak up.
That would be me. As kind as I am being, I am still getting downvotes on nearly every post. I who see violence every day and do not speak up for fear of the violence being directed at me. The "witnesses" (deceptive name) may have meant well, but they are products of the current culture, and they can not see beyond what they have been taught.
