So the only thing the article says about his actual offenses is:
First thing, it doesn’t say anything about how/why they obtained a search warrant. Second, in the picture I see 6 guns (a handgun and five long guns). Third the “sawed-off shotgun” appears to be a Shockwave with the original 14.375 in barrel, classified as a firearm by both the ATF and MA and only illegal for an FFL to transfer in MA, not for someone to own (with an LTC). Fourth, I don’t see any silencers, but I do see what appears to be a ballistic vest. Fifth, I don’t see any threaded barrels, though the pistol might have one and the PCC 2nd from the right end might also. Don’t know why someone would have silencers without any guns to mount them on. Sixth, I see ten poly ammo cans, not “15 boxes of ammunition”.
I’m really interested in why they pulled a search warrant on this guy. Did someone drop a dime? Were they investigating him for some other crime? Were they investigating him for his social media comments?
I’m also unimpressed with the accuracy of the reporting. Either the photo posted with the article is wrong or the reporting is wrong or the reporter is depending on the police report that is wrong. In any case the reporting doesn’t go with the photo.
