Can you help me decide whether to go to a very large funeral?

The wife of a police lieutenant/firefighter killed on Christmas Eve morning is a friend of my family. Actually our parents are very good friends. I care about her very much and initially planned on going to the funeral. However, according to a group on facebook, funeral attendee estimates are currently around 10,000 people.

1. I can’t even imagine the logistics of such a crowd. I would imagine having to show up very early to be able to be seated indoors.
2. I doubt very much that I would be able to see, let alone interact, with the wife.

I feel a slight sense of obligation… but mostly I feel completely overwhelmed by the prospect. Can you help me figure out if I should go?
