Defunding the police addresses the overspending. Despite millions of dollars for training, outcomes in police interactions haven't gotten better. Purchasing military surplus is another area they've spent increased budgets on as well.
Police only pay for shipping. If those costs are swelling their expenses, they have a tiny budget.
The 1988 National Defense Authorization Act created a temporary program within the DoD to funnel surplus equipment to state law enforcement agencies involved in anti-drug activities at no cost other than shipping. The 1997 National Defense Authorization Act added anti-terrorism activities and made the program permanent.
(Hint: barely anything)
By which metric?
It's not a single-metric question though. Probably not just a 10-20 metric question either.
