Oh look, midterms are coming up, need a plan to gin up sympathy for the Democrats and play the victim so they've got another reason to blame Trump for.
Also another suspicious package was found today at Obama's home

Ok
Post markings - not everything that gets posted gets watermarked/stamped especially irregular shaped packaged (and there are sometimes issues with the stamps themselves not taking the markings) - I've lost track of the number of items of post over the years I've received that hasn't been marked (the main reason for the stamping is to invalidate the stamp, the postal services aren't too particular about it if the machine that does it isn't working, and if you bung something in a letter box it bypasses what is usually the only time someone manually does it).
Not enough postage - if it's like the UK the receiver gets billed for the under paid postage and you can bet something like CNN will likely have an agreement/account for such things (as anonymous sources may send things in with incorrect postage).
Wow incorrect name spelling, that always stops things arriving and it's so unknown for idiots who are posting explosives to get the name wrong.
OMG a building address that is incorrect or incomplete, the postal services never have to deal with that before - oh apart from the fact that if you put "BBC London" and post it in the US or "CNN New York" posted in the UK/Canada etc or "Fox News, fantasy land" posted in America it'll probably get there if not straight to the right department inside the company (the postal services have over a century of dealing with poorly addressed mail that is far, far harder to deliver than a well known name in a big city*).
Besides anything else postal services usually work on building/business name, so it doesn't matter if you send something to John Smith who doesn't exist if the building address is sufficiently good (part of the reason you still get cards addressed to someone who moved away/died 20 years ago).
Someone took a picture- people have never, ever done anything silly like that before (well apart from the fact I've seen fire procedure signs with notes like "wait until you get outside to post on social media"), or that journalists will take pictures and with the modern phones it's a couple of seconds to do so, not setting up a tripod, lighting and waiting 30 seconds for the plate to be exposed (not to mention they may have taken a picture when calling the police). I mean it's not like a possible bomb at a news outlet is going to be of interest to anyone, or get reported on.
*Read up on how RM deal with poorly addressed mail - they've got a department that can work out "John, by the water mill in Devon" and similar gems
