Typically the AI isn't considered the same as an officer for witnessing. The officer clause is so an officer watching a beatdown doesn't have to go "sorry lmao i dont got a warrant : ("
Witnessing something as crew, command, AI, etc. can be used as evidence, but you should still be getting a warrant under standard operations. With that said, if the AI or any other crew is witnessing something that requires immediate sec attention like an attack, calling for them will 80% of the time get an officer there quick enough to just straight up witness what's going down.
Edit: Oh right and the actual main point of the thread. I'm more supportive of the idea that arrest warrants should still be required on blue. Excuse search warrants? Sure. When there's a possible threat it makes sense to allow immediate searches of any crew and to let sec act on what they might find through that search. Not really enough of an excuse though to start detaining crew on suspicion alone though. I'd leave it to code red to no longer require an arrest warrant as red alert typically means things have escalated to the point where efficiency is what's needed most. Still waiting on FT to drop his post here.
