I'm going out on a limb here, but I'm not hang-wringing over Uruguay, and I've long since accepted that we lost in '86. Yes it was handball, no it wasn't given. What are you going to about it now?
Things happen; Sportsmen at the highest levels to what they can to win, for themselves or for the team. Cricketers don't walk, sprinters 'anticipate' the start rather than wait for the gun, darts players talk whilst the other is throwing, car designers use loopholes, drivers minimise the available space to overtake, it's all been going on for years, and always will. It's a very romantic notion of play to the rules, jolly good show, let the better man/woman/team win, but it's not been that way for many, many years.
Had it been England, well, I wouldn't have been 'proud' of it, but I'd understand why the player did what he did - It's the dying moments of a WC QF, and given the 2 teams involved, a once in a career opportunity to get to the semi final. Again, had it been England, and the player not handballed, he'd be criticised for not preventing a goal by any means necessary.
