Ok. If English is not your first language, you have a pretty good mastery of it, so well done there. Here is an extract from the Law as it currently stands. I have posted it earlier in this thread or the 'Is Football Bent?' thread, and it has been discussed before.
According to the Law, Laporte must have deliberately touched the ball with his hand (he didnt) or either he himself gained possession of the ball after it touched his hand (he didn't) or he himself control the ball after it touched his hand (he didn't) for the offence of handball to have been committed. So under the Law, Laporte did not commit handball, so the goal should have stood.
Because of this, I emailed David Elleray of IFAB and asked if our referees were interpreting the Law correctly. He avoided answering directly. Instead, he explained that when asked, football players, coaches etc. confirmed that they did not think a goal should be allowed if the ball touched the hand of a member of the scoring team in the build up to the goal. This is why we have this 'what football wants' concept.
What we are left with is referees, assistant referees, VARs and their bosses becoming ever more creative in their excuses for why they are doing what they are doing. They are forever trying to justify why their decisions are based on 'what football wants' rather than just applying the Law as it is currently written.
What they should be doing is applying the strict letter of the Law, and waiting until next season to change the Law so that it actually delivers 'what football wants'.
