That was a very bad night for everyone involved and the feed should of been taken down for respect and safety of all.
Greetings...
You are right about the first part, BUT I feel you are wrong on the second part. I think it is important that for people to hear what people in public safety endure during unfortunate events like this. I am speaking from both as a scanner listener and as a person who works in public safety. I have been a police dispatcher for a large city for more years than I would like to admit. Too many people outside of public safety (media for example) are quick to make judgement if something goes haywire. I place hearing the radio traffic right up there with releasing 'body camera' video. People may change their opinions when they see and hear what transpired during an event.
Even more important is that other people in public safety (Dispatchers, Police, Fire, EMS, Etc) can learn from each of these unfortunate events. Since I work in a big city I don't think it benefits me as much as someone who works in a relatively smaller city (population 100,000, etc) to hear this type of radio traffic. Also, this type of radio traffic can be used to train new police dispatchers. This is very helpful since you can't re-create a critical incident (speaking from plenty of experience) during the training process.
Unfortunately, most of these suspects expect to be dead by the end of the event (Either suicide or killed by officers). I don't think in these cases broadcasting the radio traffic would help the suspect as much as you would think. With hostage situations and critical incidents like that, the feed should be taken down or perhaps have the feeds delayed by a certain length of time (10 or 15 minutes ?).
