Under the right circumstances, police may force entry into a home when doing a welfare check. Usually they will walk around and look in the windows and if they see/hear/smell anything unusual, they do actually have the right to enter. They have to look at mail dates, things left on porch steps (newspapers piled up), etc etc to determine if perhaps the person is incapacitated/dead inside. If they didn't do any of that or didn't see anything suspicious, then I doubt they were legally allowed to enter, so I'm not sure why that would've happened. Maybe your T had told them you were at high risk for suicidal behavior (I'm not saying you are, I'm just thinking about what might have led the police to enter without permission)? Sorry that happened TC, hope things get sorted out between you and your T. I would definitely tell her that she needs to call you before she does any of that again!
