He also inherited one of the guns from a friend in Canada in 2009, despite being barred from gun ownership after a 2002 conviction, and the RCMP failed to act on information about his illegal gun stash in at least 2011 and 2013.

Wikipedia also disagrees with the sources of the guns. Of the five, one rifle he inherited, the other was bought by a friend at a gun store in California and then given to him. He acquired one pistol from the guy in the article, another was loaned to him by someone else, and the fifth was a service pistol from one of the cops he shot. Nothing about a gun show in Houlton.

>It's illegal to gift or sell firearms to a foreign national/non-resident in the USA.

This is incorrect. Info from the ATF:

And a business set up to make the process easy:

A) it is not illegal for a US resident to give a Canadian resident a gun. There is a procedure for it, which afaics was not followed.
B) That's federal law, not state. ATF, which is a federal agency, is obviously aware and has declined to prosecute him. Ask them for answers, not r/Maine.
C) we're not talking about a black market arms dealer here. We're talking about a guy who trusted someone enough to invite them into their home, work on their home, and gift them a firearm. This is not the crime of the century, it's a procedural oversight.

What more do you want? They know where the guns came from. Not just a general area, they know the guy that gave him one and he stole 2 others from. Do you need them to trace the exact path they took across the border? Question the gun's friends and relatives to find out if they might also be planning mass shootings? It sounds like the investigation is concluded because there's nothing left to investigate.

Because one Canadian nut smuggled 3 handguns from Maine into Canada? This very much sounds like Canadian border agents screwed up. This is not something that Maine laws or regulations would have had much effect on - the handgun that was gifted, possibly, but the 2 that were stolen? The guy still would have stolen them and smuggled them, his corpse would just be guilty of a few more crimes.

You're looking for someone to blame. Stop trying to make it our fault.

The relevant section of this report is discussing potential sources of funding for EV infrastructure, and groups "gas tax" with other potential funding sources. It does not specifically advocate for raising the gas tax, notes the constitutional issue, and most importantly, this report was not written by Mills, rather an office under her.

I think it wouldn't be as bad if they made it clear that it was in UPS's possession and that it was in Chelmsford at the UPS distribution center there.
