Every now and then, I start thinking about no-knock warrants and how I and my wife would be dead if they accidentally executed one on my residence by mistake. Is there any way to prevent being killed during a mistake no-knock warrant without letting down your guard against a BG barging into your house in the middle of the night? Does this type of situation concern anyone else? What sort of liability would the police officers have if they no-knocked the wrong house (honest mistake) and killed the residents for pointing guns at them? It seems like the answer could very-well be "none" and that concerns me.
