1) why no body cam footage - Unsure
2) The raid was a surprise drug search. I am guessing given Breonna Taylor’s background, that she was not the target, but that her boyfriend was - is this true? - This was part of a series of raids conducted at a string of locations that night. Various houses had been used for drug and money movement. Breona Taylor's previous boyfriend had used her to hold his money and called her from jail to bail him out multiple times. I don't have the exact quote, but something like "she holds for me." Conversations were recorded from jail phones... I guess that is legal?
3) If 2 is the case, did they know ahead of time that the boyfriend could be violent? - Don't know and not clear that the police even knew he would be there.
4) If 3 is the case, then why carry out a raid that puts innocents in a potential threatening situation, and the police in an impossible situation. Good question... as I understand it, the money and drugs move around so the raids were to try to cover all locations at once? Again, just my understanding.
For everyone involved, I do believe it would be good to open up all the facts. This would help with the logic of what the police were doing, and see if it was "just" with the potential issue of soiling the image of the dead...
When I see a no win scenario like this, I ask myself if the situation should have been avoided higher up.
