Bingo!
Most civilian SWAT variants are trained in dynamic entry. They might have a couple of snipers trained up to 200 yards or so. Whaddathey gonna do when they are in more open terrain and dozens or hundreds of guys are hitting them from 1-2-4 or more hundred yards, with .50, .308, 30-06, 300 Win mag, 443 Weatherby, 338 Lapua...you get my drift.
They ain’t gonna do so well.

When I’m home I take my .22-250 Savage out to eastern WA and shoot prairie dogs. It’s sighted in at 500yds. I’ve hit them out to 700. I use a 4000fps varmint round.
