No, SWAT teams were initially designed to end already violent situations (armed robberies, riots, hostage situations, …), however they were designed to be called in after threat assessment and tentative deescalation (by regular police units or negotiators)

I couldn't agree more.
SWAT teams were never designed for "first response" but for "overwhelming response", they're police's special ops/SMU, but nowadays they're just a cowboy unit being sent on any trouble without any sort of situational awareness or threat assessment, better training of the SWAT units would be unlikely to help. Not to mention with the militarisation of US police (hands-me-down army and the like) having a "SWAT team" and using it for any and every thing has become a mark of rank/pride for every fucking podunk town sheriff or police office.
Back in 2014 there were ~80000 SWAT actions per year in the US, and only about 7% even remotely had anything to do with the original purpose of SWAT teams (hostage situations, barricades, significant armed robbery, …): https://www.aclu.org/blog/another-day-another-124-violent-sw...
