Well, what it says is definitely not great, but in this specific case it's probably a bit less about the police overreaction and a bit more about the prevalence of guns and how to safely proceed when notified about
extremely volatile and dangerous situations, such as a hostage situation with an armed individual that is exhibiting signs of mental instability (whether true or not).
How the police respond may be weighted too much towards a specific action, but it's important to consider this is the actual reason that SWAT teams exist.
I would definitely be interested in knowing how situations like this are handled in other countries, and the success rates involved. My suspicion is that in countries without the equivalent of SWAT some scenarios don't have an adequate response, while others that we use SWAT somewhat inappropriately for that are handled better. I suspect a less military approach is better overall, but an entire lack of that option isn't beneficial either. I don't think it's hard to argue that there's far too much police militarization in the U.S. right now.
