I think there's some merit to blaming the reporter for being negligent. But it's important to note that that does not in any way, shape or form excuse the behavior of the police in this matter.
Frankly, I think individual officers in cases like these should be held personally responsible for infractions they commit, even if they're just following orders, and even if they didn't know any better. It happens all too frequently that some anonymous police or other organization gets blamed, and the consequences to anyone personally are then irrelevant at best. Perhaps some committee harasses those involved; or the police pays some fine (but that's really the taxpayers paying it, after all) - but at the end of the day, the actual people that in all likelihood intentionally violated other's rights get away scott free.
And there's no pushback from inside the organization, because, well, nobody ever got fired for following orders when there's even a whiff of plausible deniability here. Nobody is taking responsibility for their own actions; so it shouldn't surprise anyone that the police act irresponsibly and unethically despite the fact that most people involved only ever had the best of intentions. If you want it to be normal for the officers in a raid to question the need for it, the circumstances in which it is made, the force with which it is executed, or the damage that is done to those they raid, then there's got to be an incentive for officers to push back and do what's right. Right now, we reward officers for doing what's wrong and punish them for thinking and having a conscience, and that is deeply disturbing.
