I don't have sure answers to your question, but I can speculate. The response time between the report and arrival of LE is not instant, implying an inevitable delay. This might be reason to not necessarily rush in too quickly, i.e. the situation may have changed. In such an immediate scenario as you've proposed, there is definitely a maximum priority, and multiple factors to consider, e.g. hostages?; number of victims/assailants; style and material of attack; reliability of report and probably much more. I'll admit that I am not qualified to evaluate this variety of scenario. However, from what I've observed, most botched SWAT raids don't involve such a critical priority - and that is a problem. Oddly, there was, by some standards, a highly dubious delay in the SWAT response to the Orlando Pulse event, where things may or may not have ended very differently. I wholly concur that a much greater burden of responsibility is needed. In so many situations, there is no substantial accountability and either someone's life or dignity is lost for no legitimate reason. Not good for citizen morale.
