But not so much between "this person walked in my door and stole my stuff" and "I left the door to my house open and then I put my stuff in the doorway."

Flock cameras are roughly that secure.

Isn't Flock more like a house sitter in the analogy though?

"I gave the person keys to my house and then I trusted they wouldn't open bathroom doors while somebody was there".

Like law enforcement is being given access to the systems, the door isn't "left open", a key was given to them.
