Grady had cops and gardeners on rooftops nearby, yet they didn't see all that smoke that Daryl created when he burned the bodies? They could have easily found and killed them. If they had been watching them, they wouldn't have left Daryl alive if they had meant to hit Carol on purpose. Yet another odd mystery surrounding this episode.

 

I agree about the cops' intentions. They would've seen the car Daryl and Carol were in anyway when their car had stopped and the walker was growling in Carol's window. (The cops would have just passed that spot where there was no car earlier.)

The bigger point is that Daryl and Carol had just sneaked through the city, sticking close to buildings and such to not be seen. Then Daryl builds a bonfire??? The flashbacks of the smoking shack and prison show that Carol SHOULD know smoke can be seen from a distance, too. Yet she didn't realize it either when the bodies were being burned? The scene just contradicts so much just in the same episode, let alone the rest of the series.

Sorry, but is the writing and directing THAT bad, or are Daryl and Carol really that stupid?

 

They probably knew all along that Daryl and Carol were moving closer (and had weapons), which is why the car that hit Carol was nearby.
Had the timing been slightly different, a confrontation with the cops on the street would have been funny:

Daryl and Carol - "How did you find us?"
Cop "We saw your smoke signals, dumb asses"

 

But the fire was less than 2 blocks from the hospital and coming from a building. With all the paper littering the streets, the cops should be concerned about the whole city easily burning down, anyway
