Did the cheering during President Obama's speech today at the Arizona shooting memorial seem inappropriate?

I've always said that at my funeral I would hope people are celebrating and having a good time, but after hearing the cheers from the crowd today during a memorial, it just doesn't sound right anymore. Even though the crowd clearly didn't mean to be inappropriate, it still ended up sounding that way, don't you think? It felt more like a concert or a pep rally to hear cheers like that, when it seems to be more of a time for a somber remembrance. That's not to be political divisive one way or the other (I voted for Obama and I liked his speech today) but I'm curious, doesn't cheering at a memorial, like the way it happened today during his speech, seem weird at something like a memorial? I mean, I know we all deal with grief in our own ways, but is the behavior of those cheering more suited to a the bar afterwards and not during the memorial?
