It's only because:
1) It made the news originally
and 2) The subject was an active law enforcement officer.
Otherwise, the courts really don't EVER prosecute for perjury no matter how bad the offense - even if they are outright forging documents for civil proceedings... So you and I don't get this kind of consideration.
Seen it a lot, worked it a lot, fought it, doesn't do any good. Just how our system works. Same thing applies to the Sheriff refusing to serve.
If it were me, I'd much prefer the system worked identically for MR. LEO as it does for Bob down the street, so people know what to expect. I wish they served it. (and brushed the perjury aside because the courts always have more important things to do than to protect the integrity of the courts)
