I chose to restate it in other words so maybe jolly would get it.
eye retina scanners at them. You will have to look into them before entry and all who have been convicted will be denied access.
What is there to "get" apart from the fact that once again you are trying to discuss something that you have no clue about. This thread is about football hooliganism in Poland, not about current events in the U.S. . Is that so hard for you to understand?
Regarding the eye scanners, if you would have the slightest clue about Poland or Polish football, you would know that appropriate measures have been introduced at Polish football stadia already.
However, Concordia Knurow plays in the fifth Polish league where measures such as the ones introduced at higher level clubs, simply do not make sense because they normally wouldn't have the attendance needed to justify such measures. Usually everyone would know each other on the stands anyway. No point to have an eye-scanner, "karta kibica" etc. if the "stadium's" fences can easily be climbed over too.
The problem is not the security measures that have been introduced. The problem is the follow up. Legia Warsaw is a fine example. The capo of their Ultras has been banned from the stadium several times, yet he lifted the Polish Cup in the stands of the stadium when a player went to bring it to him.
In any case, last weekend the police overreacted. There was no need to use rubber bullets as there were plenty of police to keep the two sides apart. In my opnion, and watching the video over and over again, the cop that shot the gun felt secure and safe not to attract any media attention in a 5th league Polish game, so he decided to use the gun to demonstrate "his strength".
