I will say this. Cops, like teachers, don't need to be composed of the lower strata of income level.
If so, you get what you pay for and society suffers at the end.
Great point,

It would be interesting to see how much $ is spent on military-grade technology for police.
Like most government, I'm sure there are grants where the money can only be spent on equipment rather than personnel.
The police do need to be trained to be more tactful, but even more important IMO is that departments need to be able to pay a decent wage to good cops. Just like teachers, it's a shame that the people we depend on so heavily in our society are paid such a meager wage.
