Not a silly question. If you go back to the 2000s, you'll see the growing militarization of local police. This is partially an economic prop-up where the military can now sell police departments materials/arms/etc. and police departments can buy them. Thus the military needs more. Nice little situation they found.

At the same time as these departments getting more funding, it feels like most departments have decided its better to use taxpayer funds to settle court cases rather than train and be more selective.
