I think you're looking too deeply into this and trying to create a consipiracy where there isn't one which is surprising because I follow your posts on the development and construction pages to do with the Etihad so I thought you'd be more clued up. The whole stand should have been open in August, but it wasn't because of Buckingham Group going under and they had failed to meet the timescales required. They've played half the season with a fully reduced capacity because of it and only in the past 2 months have they been allowed to have any fans in the top tier. Bear in mind that a top tier, albeit a much smaller one, existed before this season but was completely out of action for 4 months.
I'm all for having a pop at Liverpool. I can't stand them. But there is a hole in the away section that was taken out during the off season when the roof and existing top tier of the old stand was removed. The hole contained supports for that roof hence why it had to be done. They can't fill this and put the concrete in until the season has finished because it requires a crane at pitch level. Have a watch of Mister Drone's Anfield updates for more info.
Also, I don't think Liverpool have ever reduced our allocation before. I'm actually dead against the reduction of any away allocation including ones that the Safety Advisory Group keep doing for United and Liverpool at our place. The police are paid enough money by clubs and by the Premier League each season to enable them to police 3,000 away fans. Reducing by a few hundred should make zero difference. It sets a dangerous precendent and one that we should be dead against because it'll only end up in clubs going tit for tat and we'll end up being in the same boat as the old firm with little or no allocations for away fans if we aren't careful.
