Your Point #1. If that proves to be true after an investigation, then it should be a slam dunk to take him/her and his/her jurisdiction to the cleaners and by that result, the policy and training gets changed if the policy is in error. In many of those situations it is true that the officers acted appropriately per their training/policy, the jurisdiction/Chief doesn't get sued and/or lose and nothing gets changed. You know who writes those policies these days? Attorneys.
Your Point #2. This is true for all professions, including yours.
I find it curious/interesting that 2 members of the legal profession are complaining about something that they have the training (and probably the wherewithal) to do something about and yet, apparently haven't, because one thinks it's bad for business (CWV) and you because?
My point is, that if it is morally and ethically wrong to do, (which is open to argument), there are avenues of redress built into the legal system. Why haven't those with which you take issue been addressed? For instance, Miranda, wasn't always required to be given for someone considered to be in custody. Now it is because someone took it to court and won?
