Unfair.
The SWAT guys followed doctrine, which assumed a standoff, negotiations, etc. Perfectly reasonable doctrine appropriate for what happened in the past.
New situation means the old doctrine was inadequate.
Just as on 9/11 the doctrine was that in a hijacking you did as you were told, flew around for a few hours or days in discomfort, then sold your story for a bunch of money.
SWAT and airline passengers now have different doctrines.
If local police are going to try to support a quasi-military arm without looking like keystone kops, they should be at least as savvy on war scenarios as our actual military is. You want to “negotiate” with a guy who has been shooting innocents down in cold blood for no reason? Mais non.
