"The officers observe a bald headed man, about 50 years old lying face up in his living room. The man is lying in a pool of blood. The officers tape off the crime scene, make all necessary notifications, and begin to interview five neighbors to find out if they saw or heard anything related to the death of Mr. Cain."
Stay awhile and listen, for this is how Cain dies in Diablo 3.
Didn't check for a pulse. Didn't administer CPR until medics or someone else arrived to relieve him.
Maybe he was able to conclusively determine that he was gone. Not enough information is given I suppose. I didn't know beat cops in NYC were coroners or medics...
I don't know the situation in NYC, but in many places, any medical intervention can be contraindicated by certain signs of death (injury incompatible with life, rigor, hypostasis, etc).
It is pretty common for police to have first responder training, as they are often literally the first to respond to medical emergencies by dint of already being in the area.
OTOH, if you are responding to a scene where someone's head is bashed in, there's really not much point in attempting CPR...
I am guessing that at least partially, it is designed to replicate what is likely a common scenario with police officers in which they are questioning someone who has either just been a victim or is potentially being deceptive/closed off/whatever. I wouldn't be surprised if very often when questioning someone after, say, a mugging, the actual details and faces to names doesn't happen until a few sentences in.
"My brother was standing next to me and the guy came up and stole my backpack."
"Ok, and you were standing over there? Over by the stop sign?"
