The biggest risk to DC is us not fulfilling our fixtures. It makes total sense to cause him as much pain as possible by preventing games finishing. I imagine he will get huge fines for this that would eventually squeeze him out the club.
However, It sounds like the new CCTV system is DC preparing for this & it sounds like he has plenty of security staff at the club still willing to fight for him. It will be much easier for this to be managed in only 2 home stands.
I think those who go on the pitch in the first home game will be made an example of. Immediate ban which will be enforced via the facial recognition & DC will enjoy spending whatever money is required to get them convicted as a criminal.
Whatever happens needs to be organised & done on a big scale
