Nothing USEFUL.
Just political panderings and negative actions. The BCI would typically be called in to review cop shootings anyway unless it was clear cut (and maybe even then). They come in and rubber stamp the local investigation of an OIS, yay.
It's akin to the climate change. The "legislation" passed under some guise of reducing inflation would spend about $37 billion a year on climate change stuff.
That's a great example of my point. Throw a bit of money at it.
The various estimates for the cost to reach "net zero" by 2050 hover around $50 TRILLION. With a "T", call it $2 TRILLIOn a year, which probably also isn't enough. We allocated billions to build, so far, EIGHT EV charging stations. The private sector has built many more than that in the same time period.
I personally witnessed two "BLM Protests", both were mostly young white folks signaling how they aren't racists. Then they returned to their lattes and $3K a month apartments and felt smug. The police here disappeared for about a week. They just parked their cruisers somewhere and did a "blue out", I witnessed this personally as well, as we usually see police out and about when we walk. And crime went up. Yay.
Fortunately, that is back to normal around here pretty much.
I'm all for legal sane protests if someone feels the need, have at it if it makes you feel better. It's not going to do anything useful with very few exceptions.
