Tbf I also heard it was a request from the police also they have had problems with fans pissing on the terraces aswell as the smoke bombs etc
There's a huge leap being made from the police raised an issue at the SAG meeting, which is what they are for, to the police demanding blocks be closed off. The later was done by Wasps as it is Wasps the club are going back to asking them to reconsider. If the police had said close them end of discussion that wouldn't be happening.
Lets look at the bigger picture.
The stewarding used to fall under the control of CCFC, overseen by someone with many years experience of working football matches. Wasps decided he wasn't up to the job they would be taking over themselves, and of course charging the club for the privilege. The chap they pushed out from CCFC was clearly so bad at his job he immediately got picked up by a Premier League team.
Since then there has been, despite smaller crowds, an increase in issues with the stewarding.
When these issues are raised at the SAG there is no longer anyone fighting CCFC's corner.
I would suggest that if we were still running things ourselves then when the police raised concerns rather than a knee jerk 'we'll close those blocks off' sensible solutions could have been found. Just off the top of my head by if I was representing CCFC at that meeting I'd be suggesting:
Increased ticket checks - they're already checked on the gate, check them as fans enter the blocks as well;
Open all the kiosks - remove a reason for fans to be wandering from block to block in the concourse;
Only sell tickets for 14-16 in advance - those stewarding the problem blocks can then be given a print out showing what seats are sold, making it easier to identify those in the wrong place;
Increase numbers of stewards and police - the problem area is not the whole block it is a few rows. you could put 5 stewards up there, each accompanied by a police officer (if they aren't too busy standing at the bottom of the block doing nothing), anyone standing in the aisle or in the wrong seat gets requested by the steward to sit in their own seat, if they don't police chuck them out;
Club communicates to fans police concerns and outlines changes being made making it clear it is zero tolerance and if the behaviour continues those blocks will be closed.
That's just of the top of my head and obviously I'm not someone who has spent years with this as my job. Just saying the first option doesn't have to be shut everything down.
