When a pilot is issued a slam dunk approach, it's a clearance for a visual approach. To execute the approach the pilot must first accept the clearance. I've turned down many approaches. And never been bashed or ridiculed for it. Not only slam dunks. Too close, bad weather, just didn't feel right. You have the option. If ORD or BOS give you a clearance for a visual and you think it's not right, refuse the clearance!
