So no, that implication really isn't there.
The lack of will to reform is not total amongst LEOs. The lack of political will to do many seemingly sensible things in this country is a moral failure that every citizen shares.
I suspect that you're right that it is a minority of LEOs that actually abuse their power (possibly a 49% minority, but possibly even as low as 10% or even 1%), but it's clear that there are many more - an overwhelming majority, who actively defend or passively ignore those who do. (I'm sure I only ever see the bad ones, but just about every statement by the Fraternal Order of Police makes me seethe with rage...)
Total lack of will to reform: no.

It seems to me there's a tremendous lack of will to reform abuses and criminal acts by LEO. Perhaps not "Total", but so marginally less than "Total" as to be functionally equivalent (in that "not all men" kind of failure to acknowledge reality...).
Police misconduct is real here and all over the world, as well, and will also continue to be fought. There are no quick fixes, and it's important to be outraged and voice one's outrage when we see it, but let's not give up and paint all LO with one brush, as their existence most certainly contributes a net positive to society.
