The local media in Denver does this voluntarily too, without admitting that they're doing it.
I just usually do an internet search on a suspects name and sure enough, POC.
Then there are those that commit some heinous crime (alledgedly) and you know that their immigration status is less than legal but the media doesn't touch that with a ten foot pole. One would think that should be their job, like they could check it out with just a click or two. But no, nothing to see here, move along.
