I would assess this as most likely a paranoid schizophrenic in a deteriorating phase who is calling on external authorities to restrain him before he does something harmful to himself or others. This is exactly how schizophrenia can work.
No, I am not a doctor and I do not play one on the Internets. Yes, I have had personal experiences dealing with schizophrenic patients. They speak a "foreign language" which requires translation. Hence the personal opinion.
Real Government agents would not have called the local police for any reason. If somehow discovered with such a stash of weapons, they would have made a single phone call, resulting in a cascade of return calls to the police and the district attorney from some higher ups. The matter would have been quietly dropped.
The Las Vegas incident has been quietly dropped, after quite a bit of visible arm-wrestling between the State and Federal officials. There is not likely a usable connection between that episode and this one. This one is a distractor.
Is it possible that people with schizophrenia can be triggered?
There was a ton of weapons in his room:
From the article:
“...Tewskbury PD posted a photo of the items found in the hotel room. These included:

- an AK-47

- a 9-millimeter gun with 2 x large capacity magazines
- a .45-caliber gun with 2 x speed loaders
- a shotgun
- numerous rounds of ammunition
- multiple smoke grenades.
Bradley had a valid gun license for Texas, but not Massachusetts, so he and his girlfriend Jennings were charged anyway, with multiple counts of weapons possessions. ...”
