An officer is at your door. What do you do? Well, here's some tips and rights that you have at your disposal.
He's at your door.
If police or immigration agents come to your door, you do NOT have to let them come in without a warrant.
If they have a warrant, ask them to slip it under the door or hold it up to the window so you can inspect it. When it comes to warrants, they only authorize the police to search the location and address listed on the warrant. Furthermore they are limited to the items and areas listed on the warrant. If the warrant is an arrest warrant, they may enter the home without consent if they believe the person named in the warrant is in the home. If the warrant removal/deportation (ICE) warrant, They may not enter without consent.
Even if they have a warrant, you have the right to remain silent. Step outside and close the door behind you. Do NOT let them in your home. Like the Child Services workers, if an officer enters your home, he is looking for anything illegal and will arrest you for anything he may find. This can also lead to a legal search of your home if the items he sees give him reasonable suspicion that there may be illegal contraband or other criminal activity happening.
Lastly, always film the police. Check the next portion for tips and rights involved in filming the police.
Filming The Police
YOU HAVE THE RIGHT TO FILM THE POLICE - In all 50 states except Illinois, you have the right to film the police during the course of their duties provided that you remain at a safe distance, do not physically interefere with their duties, be on public property or your own property, and if you are on private property, you must have the property owners permission. Police can NOT tell you to stop recording, the can not make you leave if other members of the public (without recording) are allowed to stay. They CAN order you to back up. If you are going to record the police, do it in an open and obvious manner. Under the 1st ammendment there are no circumstances where the contents of video or photographs should be deleted or destroyed. Source - Washington Post
