Whilst I tend to agree they aren't quite as nailed on as some, the first was holding, and the laws say if holding continues into the box its a penalty. The second one I think is 50/50, I don't think the slight shirt pull is enough, but coupled with the trip I'd give it. The third the pundits are talking crap, it doesn't matter at all where the ball was going, intent is the key and I think its unnatural to leave your arm in that 'frozen' position so I think its a penalty. The last one is the most obvious of all, you simply cannot throw your arms above yourself, turn your head away and say "not looking".
