UK prosecutors charge six people over 1989 Hillsborough disaster that killed 96

None of that explains how 4000 people outside the ground had a right to access WHEN THE GROUND WAS ALREADY FULL. REGARDLESS OF THE FACT THAT SALES WERE 300 LOWER THAN CAPACITY. It must surely be assumed that there was an element of forgery in ticketing to account forv 4000 extra visiters. The police have been targeted so relentlessly over this for so long, that, they have never been in a position to investigate this. Despite the mistakes they themselves made. If, there is a shady backstreet printer responsible for this, they will now never be found.

The ground wasn't full. There was plenty of space in the pens at the sides but fans weren't re-directed there. 

Your main point here was quite widely discussed but there was never any evidence of forgeries floating around in any numbers. The police had the used tickets and you can bet they would have brought the evidence out if it had been there. In fact, the West Midlands police, as part of their investigation, seized and sent a random sample of 100 used tickets for analysis to the Home Office Forensic Science Laboratory. The Senior Science Officer reported that there was "no evidence to suggest that any of the questioned ticket items to 100 are counterfeits."
