Families weren't dragged by force. Mobs, politicians and publicity seekers can't make families show up where they don't want to show up.
I heard family members talking about the lives of their loved ones. I didn't hear family members talking about the last moments and death.
"Soak, soak, soak and drown in the bitterness of the last moments" are your words. I certainly wouldn't attribute that to the family members who showed up.
The force of the mob is at the top rank of motivating forces.
And yes indeed the mob did command their appearances.
