Police Officers Knocking at your door
<p>When a police officer is knocking at your door, do they have to tell you or introduce themselves as police officers??</p>

<p>That depends on what the officer wants to do. If the officer is under cover, s/he may choose not to identify as a police officer. If the desire is to search the house, or to arrest someone, the officer(s) do need to identify themselves. If the desire is just to talk to/question a possible witness, officers normally do identify themselves, but I am not sure that this is legally required.</p>
