The police want me to give them permission to search my house, car, computer, camera, etc. Should I give it to them?
Absolutely not. Under no circumstance should you consent to a search of your person or property by law enforcement. If law enforcement is requesting consent to search they are obviously investigating you for criminal conduct. Because they are investigating you, you should not in any way facilitate their investigation. If you have reason to believe that you are being investigated for a crime, and law enforcement contacts you for purposes of obtaining a consent, never sign that consent.
