It's odd that as you're so conversant with the Constitution and state law and have already retained an attorney that you came to this forum.
This is how search procedures went here in New Mexico and I'm sure California isn't that different.
To begin, we didn't just drive round and say "That looks likely, lets break the door down", because our superiors took a dim view of that sort of behavior. With warrant in hand we would enter the house and do a 'sweep'. This is different to a search this is just checking if there is anyone else in the house. It was common to 'Terry frisk' everyone for weapons for officer safety.
Then everybody exits the house. Now in goes the Technical Services Division (TSU) photographer who takes literally hundreds of photos. The reason is two fold, to photo any evidence in plain sight and to preclude any cries of "My Ming vase and collection of Monet paintings has gone missing", or "They broke my (fill in the blank)"
The bad news for you is that found evidence of wrongdoing, and if you go to court shouting "I know my rights; the Constitution says" or "Corrupt cops", it will not help your situation, especially as many judges are former law enforcement.
