Well, this involves a bit of a deep dive.

In the 1980s, SWAT departments were a thing of municipal regions. The Los Angeles SWAT team served the whole county. The San Francisco SWAT team served the whole bay area. They were a crack team specifically for hostage-barricade situations, the kinds of incidents that inspire based on a true story action movies. At the time, we had about 500 incidents a year across the US. According to a friend who was training in the SFPD at the time, the SWAT guys were always training in the same complex as they were and were always chomping at the bit for their one or two missions a year.

Then, in the late 80s, early 90s, George H. W. Bush implemented the 1033 program. Rather than selling military hardware as surplus, it would be handed over to law enforcement. Suddenly, precincts could sign up and get an infusion of really-cool-looking hardware, like M-16 style weapons, camouflage body armor, MRAPs, tanks and so on. What typically happened is every precinct started a volunteer SWAT service, where officers could be assigned SWAT Training which was unboxing and playing with all this new military hardware. It was a ton of fun!

Of course they wanted to play with this stuff on the field, so any time there was an incident that might include the opportunity to shoot a bad-guy (that is, a suspect, typically a US citizen and civilian) they’d send their local SWAT team.

By the Aughts (George W. Bush), SWAT deployment had climbed to 50,000 incidents nationwide. 50,000-ish is also the number of dogs slain every year by law enforcement. (It’s common policy before a SWAT raid to kill any dogs on the premises, so there’s some correlation, but also police in the US just like to shoot dogs.) SWAT is now used to serve just about any warrant, and routinely kills people at wrong addresses. Obama ceased the 1033 program after the killing of Michael Brown and the Ferguson unrest in 2014 (which put on sharp display how Missouri police are poorly-disciplined and heavily armed, drawing a lot of criticism from the actual military). But Trump and Sessions reinstated it, and now it’s a pretty permanent thing. In fact, we’ve had some racketeers create precincts, get bunches of equipment which were then sold to foreign NGOs for a killing. In the United States, oversight of law enforcement is much like oversight of churches, almost non-existent, so there’s lots and lots of room for abuse.

Anyway in the 2020s when we’re talking about SWAT, we’re almost never talking about the sub-department of the Special Operations Bureau of municipalities that trains every day for their one hostage-barricade incident. We’re talking about ordinary police who take a couple of weekend workshops on special tactics so they get to shoot the fun guns and wear the fancy armor. And yes, they’re glad to blast down the door of some hapless gamer because one of the gamer’s rivals social-engineered a police hotline. The United States is a really scary place.
