Pretty much it would seem.
A stand full of Rangers fans would be a different proposition to them than a section of < 100 'well fans.
The thing is though, you would expect the police could probably, at the very least, make recommendations to Rangers/SFA etc about the conduct of the fans.
Edit: thats when you start getting into details about culpability. For example, the tickets were sold to the individuals by Motherwell. It happenned in our ground etc, etc.
