Really? Even in the Motherwell support there are plenty of eejits who would do exactly that.
The bottom line is that in the 70s and 80s, there were lots of tanked up morons who, on occasion, made going to a football match a miserable experience. That is why the polis and the authorities came down heavy handed, and why alcohol was banned from the grounds.
We can argue whether it was an overreaction or not, but it's clear that is why all the extra rules and regs were put in place. It's going to take a lot longer to rid ourselves of these constraints now than it ever did to introduce them.
