Welcome to the forum. Many of us are working to change things in MD, and there are many strategies, tactics, and points-of-view as to how things should proceed in MD to bring the law there in-line with the rest of the Country. It's going to be an uphill battle, that's for sure.
The most we can hope for with the current SAF case is that MD will be forced into something like a "Shall Issue" policy for carry permits.
The current MD permits are NOT concealed carry specific permits. They are a "Permit to Carry a Handgun". There is no stipulation on the permit that it be carried concealed. In fact, with such a permit, OC is legal in most of MD.
It is the 4 "urban" counties, and most of the urban municipalities that have local laws prohibiting the "public display of a firearm" that prevent OC even to permit holders in the urban areas of MD. Those local laws will require a whole suite of additional lawsuits to get removed from the books.
It will be, in the very best possible scenario, a decade before MD even approaches "Gold Star State" status.
And even once the laws ARE changed, we can all look forward to hundreds of "color of law" persecution incidents and dozens of Federal Civil Rights lawsuits every year for another decade after that. The current AG (and most of the prospective fillers of that position for the immediate future--from BOTH parties) seems to believe that MD is not constrained by Federal Court rulings when it comes to Fundamental Rights like all the other states, and the MD LE community would rather hide behind "qualified immunity" and maintain their status quo serfdom than follow their own state's Constitution's Article 4 and do what the People mandate should be policy.
And we all know about the MD Wiretapping law shenanigans. Regardless of the fact that AG Curran released a ruling TEN YEARS AGO (in 2000) that police performing their duty in public have no "expectation of privacy", and despite the fact that there hasn't been a SINGLE conviction in MD courts for people charged with "recording a cop", the MSP and local LEAs continue to arrest and charge people with FELONY wiretapping for daring to record MD LEOs performing their duty...Art. 4. That the People of this State have the sole and exclusive right of regulating the internal government and police thereof, as a free, sovereign and independent State.
Don't expect a change in behavior with regards to firearms.
If anything, we'll probably see an increase in "questionable shootings" of law-abiding citizens by LEOs in the urban counties if Shall Issue and OC are forced onto MD by the courts.
The only celebration that OC and CC people should do in MD if these laws change, is to go out and buy some good Kevlar, and get Alan Gura on retainer...
