Broadly speaking we want Article 1, Section 16 and all applicable federal laws to be the only Maine law concerning the acquisition, possession, and carry of firearms. Obviously the USE of firearms still requires laws (noise ordinances, brandishing, discharge within city limits, lethal / non-lethal force, etc). I know we have castle doctrine, would like to see that extend beyond my walls and out to the edge of my property.
If I had to choose three, these would be the ones:
There is a legal exception for state universities which allows them to prohibit weapons on campus and in university living areas. My tax money funds these schools, the campus is public property and I've seen them bend over backwards to protect the 1st Amendment so I see no reason they should be allowed to piss on the 2nd. I don't want to OC in class but I don't like walking a half mile with a cane because I had to park off campus and leave my gun "secure" in my unattended vehicle.
The gun-free zone in and around the capitol which includes buildings owned or leased by the federal government. Probably wouldn't find traction for repealing the local security policies INSIDE these buildings, but again, those streets are public property. 2A / 1-16 should overrule anything else.
Currently in Maine you can be denied a CFP if the background check reveals a history of psychiatric disorders (specifically, declared incompetent by a judge or were at some point involuntarily confined to a psychiatric institution, in addition to other chronic conditions such as schizophrenia). I currently know of no appeals process for this but I am aware of at least one abuse of the latter which is preventing a woman from getting her CFP. Mental illness is a serious issue and I think this is generally a good protection for the same reason we don't allow felons to purchase or own guns, but the 72-hour involuntary confinement a physician can impose without court order will prevent CFP issuance, terminate sale of a firearm, and criminalize any such individual who already owns one. I would like to see a process whereby individuals who were confined, not by court order, for transient conditions could obtain a clean psychiatric bill of health from a medical provider and appeal the decision to their local police chief, state police, or the attorney general. We can't punish people forever for finding themselves in a bad situation and SEEKING HELP.
On the last one I'd appreciate corrections if I'm off the mark, or more information if someone knows of an existing process.
