I hate to disagree with you, but when I think of DEI I typically think of polices the favor the hiring of racial minorities. I am of course against such policies.
But God has surly blessed our extremely competent and world-wide-well-loved police force here in Germany. And they have consistently said that the main problem with the US police is the training they receive (and to some extent this also involves the policies they must abide by)
I think Christians must speak out against the police in the US. For a long time we taught people that we should honor the police and respect them. I love Bob Enyart, but I think even he made a mistake by teaching people this. He would talk about and sometimes even play videos of lying police officers, who lied to put pro-life activists in jail and later he is talking about how great the police are and how Christians should honor and respect them.
The US is a cess-pool of crime and filth. Unless you are lucky enough to be able to live somewhere where there is not a lot of people around you.
Most of these issues are the result of bad law and policies implemented over a long period of time. Many if not most of the people in law enforcement are generally good people with good intentions. Unfortunately, because of those bad policies and bad laws, and especially given the last several years, it has harmed their ability to crack down on crime.
