Shane has been a great source of energy and information for us in Maine, and I personally have appreciated the amount of personal sacrifice he's made championing US 2A & ME A1/S16 rights! There are many excellent folks who are working hard to continue protecting and expanding firearm related rights in our great State.
Recent news - on 4/5/2016, Maine LD 1572 - An Act To Ensure Nondiscrimination against Gun Owners in Certain Federally Subsidized Housing - was passed and signed by our Governor. LD 1572 ensures that residents (who are not disallowed persons) living in subsidized housing can possess firearms without the threat of eviction. This is the result of an incident involving a veteran living in subsidized housing (partially private, partially government funded) who purchased a firearm for his own protection (after the landlord refused to enact any type of security when the veteran complained about break-ins) and needed to use it during the 3rd break-in. Afterwards the veteran was then threatened with eviction if he continued to keep the firearm in his apartment. The law (90 days after 4/5) now protects him from being evicted.
I haven't heard about anything for June 2nd. My understanding is that this is more of a Brady/Everytown type event organized to blame the firearm and not the criminal.
PS (in a very polite tone) only coastal Maine is referred to as "Down East". I haven't heard the term "Down-Mainers" until you used it. In polite society, Maine residents are called Mainers, but we like to call ourselves Mainiacs.
