Speak to them through the closed/locked door, DO NOT open the door or exit your home unless they are serving a warrant, at which point you should be asking to see it.
Stepping outside can potentially impact your protection under different interpretations of constitutional rights and also opens the doors to a litany of manufactured charges/claims from the police to justify entering the home or seizing individuals.
- They got aggressive and threatening and/or assaulted an officer.
- I saw ______ inside the home when they opened the door.
- I detected the scent/signs of ______.
Getting back into your house once outside is infinitely more likely to trigger the cops to escalate the situation compared to never exposing yourself to that rush by not opening the door to begin with.
Not to mention the garbage where somehow an officer can place their foot/body into the open doorway of you open the door at which point if you attempt to close the door they claim assaulting an officer.
Don't open the door. Don't go outside to speak with them. If they've got a warrant they're not going to be asking.
