i read somewhere that the main objective wasn't about the friends' behavior...but rather the news coverage of such a "sensational killing". frankly, it's not very respectful to film/photograph someone's funeral without permission. even my dad got scolded by the entire extended family and friends and even his own sisters when he tried to take pictures of my maternal grandma's funeral without approval.
what more can you expect from external parties trying to get some "sensational news"? i mean, respect the dead...i feel that it isn't right. this isn't news but more like invasion of privacy already. imagine if someone in the family gets scolded for it, what more outsiders who try to invade the privacy.. you have to respect the wishes of the family, and don't judge the friends. all you have is the one sided view of netizens who saw the video and the "reporter's comments". who knows. the family/relatives might have asked them to chase the reporters away. and by the way they behave, are we gonna pass judgement and label them as gangsters? they may behave like that, but might not be gangsters.
heck, u can meet some person who can write real well on the internet, but when you meet the person, you find that his/her spoken english is horrid. so never judge a book by its cover. when you judge someone, be prepared to face judgement from another on your character. sorry to sound so serious. but just my 2 cents
