One perspective: at least 6 amendments in the Bill of Rights are directly about the relationship between the People and their police (most written prior to the concept of "police" as a separate entity from the country's militia forces/military, so not phrased as such, but is still known to directly apply). It's easy to argue that the remaining amendments all have indirect application to the police.
This seems clear evidence that the trust relationship with police was a critical ingredient to the Bill of Rights writers, an essentially a foundational principle in the US Constitution.
Aside: reviewing the Bill of Rights on Wikipedia there's a remark that as of 2018 the Third Amendment (no quartering of Soldiers) has never been invoked in a Supreme Court case. I cannot believe that the Third Amendment has never been invoked in a fight against "civil forfeiture" yet! [1] Yes, the wording of the Third Amendment specifically states "Soldier" and "home" but it seems to me clear that the intent should cover "police" under "Soldier" (again, given the document predates modern police), and "home" should be easily extendable to other private property. The more I think on it, the more I think civil forfeiture is directly a Third Amendment violation. But what do I know, I am not a lawyer.
