1)Penalty 1 - he absolutely played it deliberately and Kane is not interfering in the game. This is why linesman have to wait for a player to actually get the ball before they flag. This isn't even up for discussion, the referees were 100% correct.
2)There's a video of (I think) Mike Dean doing a little skip of celebration after correctly allowing an advantage which the team scored from. The job of the referee takes just as much mental effort as the players and they will get involved in the occasion, something they have been working their whole lives to achieve, just as anyone would. It isn't the best look but I'm not going to get offended by it. Again a pretty embarrassing response from Liverpool's fan base (clutching at straws anyone?)
1)The only discussion is that the rule interpretation is terrible. Every normal definition of interfering in play would include a situation where a defender is forced to play the ball by the presence of a (potentially) offside player. Sadly, under the current interpretations this isn't the case, and Kane is 100% onside.
2)Agreed. Referees aren't robots.
