Somebody murdered somebody else in cold blood, at the home of the latter.

The fact that the former had an anonymous, unauthenticated report is not rightly even a part of this.

This is insane.

Yes, it sucks for the officer, because he was improperly trained to give a great deal more credence to the 911 report, which in retrospect, was downright trivial to fill with false information.

I don't think that the officer is 100% culpable, even though his person was enlisted to commit this murder.

This is an obvious, huge vulnerability in society. Do we have a CVE for this?
