"Well great idea or not the SCOTUS does need a way to take action to ensure that laws that are struck down are not being enforced despite the rulings. Chicago being a prime example of where SCOTUS seems to need some kind of physical enforcement.."
That would entail a police force for the SCOTUS. Once SCOTUS has ruled, they are done with it until another case is presented to them and accepted for adjudication. The proper way to enforce a SCOTUS decision is to file civil suit against the offending agency. That is what groups like the NRA do and they seem to do a darn good job.
There are slips, but overall the civil suit route is usually successful as not many judges will scoff at SCOTUS.
