Knock Knock

So the U.S. Supreme Court has decided that law enforcement officers executing a legal warrant need not knock before breaking into a home.

Fair enough. I hereby announce that I no longer feel bound to keep my semi-automatic handguns in double-action mode.

Seems to me that the knock-and-announce rule was always more to protect the authorities, rather than the right of a citizen to have his person and property molested only upon receiving notice that the people doing so happen to be in the employ of the state.

But apparently it frustrated enough government officials that they now applaud the ruling. I wonder if that will change the first time someone kills a police officer on the assumption that he is a robber. Or shall we make an additional rule that a citizen may not fire on armed intruders until he has first asked them whether they work for the government?
