Right. If cops are serving a search warrant against you, it will be because they--rightly or wrongly--suspect you of lawbreaking. If the fact that someone suspected of lawbreaking owns or may own a gun is sufficient basis for a no-knock raid, then what protection do the law-abiding people who get wrongly figured have against them?
