I take it you mean the great and the good concert goers are parking in residents' spaces? If so hardly surprising given the SECC has long had a reputation for punitive parking charges - you can't blame people for trying to avoid them. You either don't take the car and use public transport - no real excuse there given the place is served by a railway station - or take the bus.
Or you impose a visitors parking permit system on the affected streets. Alternatively you do what they do at football matches around major stadia - the cops go round earlier in the day and put yellow cones down in all the empty spaces in nearby housing estates - they certainly do that at Murrayfield - I know cos I used to go across to Edinburgh really early in the morning and secured my spot before the b*****s came around
they can't do you once you are already there. Whether they'd go to all that length for a concert venue however seems unlikely.
