4. Talk to a lawyer

If the police have a warrant or there are urgent circumstances, they have the power to enter your home or business. But if the police don't have a warrant, talk to a lawyer before you agree to let them into your home or business. 

A lawyer can help you understand what might happen if you let the police search your home without a warrant. A lawyer can help you decide whether to let the police into your home or business, or insist that they get a search warrant first.
