Got News just updated that story to say that the ATF is officially disputing it.
Also, I can tell you that the “electronic signal jamming device” part is more than likely false... because the hotel security cameras would definitely be hard-wired, and the cameras the shooter were using were probably wireless. Also, the moment “all of the cameras” in a single part of the hotel went out, security would be all over it.
If they falsely named an accomplice, they’ll be out of business.
Security camera like would have to be cut. Not buying the jamming either.
