It's not a religious or cultural thing, though, just a matter of personal preference and value systems. There were probably a 100000 Indians (as in non-christian or whatever) and a thousand Europeans, but some took their hats off and the vast majority didn't. Don't know why this is such a big deal.
I beg to differ, BRK. As Buttoneer correctly pointed out, this is Christian/European tradition to pay respect. I do however agree with you (being in attendance myself in the past to a such event), that in cumulative noise at such gatherings sometimes timing is off, and people miss the moment.
I have seen Schumacher taking his cap off several times in the past to pay respect, which is why I believe what ivan
said, that after RTL interview that took prior the minute silence, he was probably rushed to make a picture, was one of the last to arrive, and before he realized what is going on there was a photo shot done. This is very plausible explanation.
I was trying to search internet about this subject, but this is the only place I came accross, which is making a deal out of it. So, at the conclusion I do not know what happened exactly, but watching a man for years, my bet is on misunderstanding, and not worth further discussion.
