Biggest issue is that the military suppliers that end up giving local PDs all this war tech are being paid federally on an untouchable military budget. They produce the flashbangs outside market conditions at all and under guaranteed federal contracts, and when the US military doesn't actually need more tanks, APVs, and flashbangs they get raffled off to police departments.

So build your personnel sensing flashbang, these PD's won't get them, they rarely pay for this stuff. Its mostly free, or at least its on a fixed grant they need to spend or lose. There is no real market for a police department to deploy tanks and SWAT in a town of a thousand people.
