It's always a hot topic for debate, this. The game has changed so much over the last 20 years, for better or for worse, and continues to evolve at an ever increasing rate. Likewise, technology improves and begins to encroach on the game at various junctures.
I am still a firm believer that the referee's decision is final. It has been the basis of the game for years, and should continue to be even in these times of questionable sportsmanship and cretinous has-beens who make a living from sitting in a studio picking apart decisions with the aid of TV replays and such. They fail to realise they only discredit themselves in doing so, and more importantly, throw away the opportunity to celebrate all that is great about our beautiful game in preference to exercising the journalist's predisposition for bitterness and hatred.
Having said that, I do think there is a place for technology to be used to aid the referees *at the referee's sole discretion*. It should not be the privilege of frustrated managers, angry twits in the press boxes or TV studios, club owners, coaches or players to call for any particular situation to be reviewed using technology. It should fall upon the ref and the ref alone to call for a review if, and only if, he is unable to make a decision on a particular incident. Once that decision has been made, players should abide by it and conduct themselves accordingly.
There needs to be a protocol set before the scavengers in the press turn the game upside down.
Bad decisions have been made, and they will continue to be made. It is all part of our great game that we, as football lovers, should learn to accept as part of the game.
