Let's face it. Regardless of the legalisms the Justice Department spews at us on the subject of no-knock raids, such a raid is clearly un-Constitutional. No self-respecting officer would ever participate in such an action. Which means the only ones who do are uniformed criminals.
Step 1: Make sure you always lock your doors and windows. Like all theives, it won't stop them, but it will slow them down, and may provide evidence they've been in your house. Also works well against ordinary burglars, and light-fingered hobbits.
Step 2: Reinforce your doors. A steel door with a well-secured steel frame takes several swings with a ram; especially if you have more than one bolt to break.
Step 2a: You know those floor to ceiling glass windows framing your entry door make it really easy to get into your home? Get rid of them.
Step 2b: That includes your pretty sliding french doors to the patio.
Step 3: Have 911 on speed dial for your cell phone, land line, and your cable connection. That gives 3 means of alerting your local police department that you're being broken into by forces unknown. The hard lines can be cut, but it's harder to jam a cell signal without alerting other people. When you do reach the 911 operator, tell them to send EVERYTHING! Police, Fire, and Ambulance. Because if it's a no-knock raid, those animals are coming in with the intention of seriously hurting you and your family.
Step 4: Use all three of those communication lines to try to contact your lawyer, and the news media. Bad cops HATE legal eagles and being put under bright lights by nosy reporters.
Step 5: Make sure that you and your family say absolutely nothing except: "Where is your warrant?" "I invoke my right to silence." "I want to speak to my lawyer."
