[The Matrix] Why didn't the agents take over a body of a cop near Trinity at the beginning?

We know that anyone plugged in is a part of the system and no one can be trusted. I know the first scene was shot before the rest of the movie as a showcase for what they could do, but it was so much easier for Trin.

 On a related note, what happens when your friend who is a cop is turned into an Agent? Do they just forget about them? Is their mind erased? Does the person disappear form the Matrix?

"No, Lieutenant, your men are already dead.". Smith knows it because he would have taken them over if them if they weren't. By the time the Agents arrive, those men were already dead, we just didn't see it in sequence.

I also assume that the Agents can't possibly monitor the entire Matrix at once, otherwise Morpheus and the Gang would be spotted the moment someone connected to the Matrix sees them.

They can manipulate your perceptions, they interrogated Neo, sealed his mouth shut, implanted a shrimp tracker into his stomach and passed it off as a dream.

I assume if they still lived, that's what would happen and if not, a suitable cover story is used to maintain the illusion.
