The Fourth Amendment protects you against unreasonable searches and seizures. If the police want to search your house without your consent, they need a warrant. Warrants may only be issued upon a showing of probable cause, supported by an affidavit. The facts contained in the affidavit must do more than support a mere suspicion. The test is whether the information in the affidavit would justify a person of prudence and caution in believing that an offense is being committed, e.g. that "prohibited" weapons can be found on your premises.
The requirement of probable cause for the issuance of warrants is one of your most precious constitutional protections. NEVER GIVE THE AUTHORITIES YOUR CONSENT TO SEARCH YOUR HOUSE, YOUR CAR, YOUR PLACE OF BUSINESS, OR ANY OTHER PREMISES UNDER YOUR CONTROL. Consent dispenses with the necessity of probable cause. While lacking probable cause, if the police conduct a search with your consent and seize evidence for use against you in court, your lawyer will not be able to suppress it on the basis that the search was warrantless.
The Fifth Amendment protects you against giving evidence against yourself, i.e., your right to remain silent. Just as you cannot be compelled to testify against yourself in a criminal trial,
neither can you be compelled to answer a policeman's questions about that AR-15 you bought a couple of years ago and never surrendered. Don't be bashful about invoking this right. It's always better to remain silent and appear guilty than to open your mouth and prove it.
At the outset of any contact with the police, ask them if they have a warrant to search your premises, or a warrant for your arrest. Without one or the other, don't let them inside your front door. If they have neither, politely request that they leave and gently close the door. If you have an attorney, keep one of his cards in your wallet. Give it to the officer in charge and request that all inquiries be made through your counsel.
Remember, the police wouldn't be at your doorstep if you were not the target of a criminal investigation. You have no obligation whatsoever to cooperate with people who intend to unlawfully confiscate your property and put you in jail. They can't arrest you for keeping your mouth shut and going about your business.
