It seems clear that the issues were a combination of (at least) three factors: the organizational concept/police, locals trying to force their way in and the
behavior of Liverpool fans / fake tickets. Cue British journalists trying to blame it all on the first two groups and absolving the third.
In saying it was the French youths causing the
initial problem you're already absorbing the clearly biased reporting.
Pertinent questions would be for example:
-how many Liverpool fans tried to use a faked ticket?
-when did the incident of Liverpool fans breaking through an entrance occur?
Because the answer to either question could (to a degree) explain the strategy of the police.
