Within reason, always do what responding officers say to do, keeping in mind they may not have the whole story. I work for a large agency, and the only way to keep the patrol radio channels clear enough to use is for the region to be divided into master districts, with one or two master districts per channel. If there is a home invasion happening in Northwest, the officers working that channel with hear the call information recited by their dispatcher. On my channel, Central, I will hear, "Fox* and K9 on Northwest!" OK, so I am driving along the Loop feeder road, the boundary between Central and Northwest. Being dutiful, I switch one radio to Northwest channel, and use my MDT to see what is happening.
BAM! I see I am less than a block from a home invasion, in progress. I will be the first arriving officer, but I have NOT heard the descriptions of the good and bad guys. OK, so I pull out my reading glasses, and pull up the call on the MDT. Or, do I? Perhaps I hear an update on the radio, that the situation has deteriorated, requiring an immediate response. Perhaps I am already right in front of the address, making myself a target, and therefore must dim the MDT screen and keep my safety glasses on, not sit there and read the call details. Perhaps the first Northwest officer has arrived, and needs help NOW!
In any of the just-mentioned scenarios, I will not know the homeowner from Adam, even if the 911 operator or EC operator got all the details right.
Oh, and don't try to handcuff a suspect alone. The quotes provided from the other thread, by a moderator, look awfully familiar.
*Fox = short for Foxtrot, the call sign for the helicopters. If there is an emergency call anywhere in the area, a message will flash to all dispatchers to broadcast that any available/nearby aircraft and K9 units, and any other available unit in the area, switch to the channel where the emergency call is occurring.
