Clearly you are the one who fails to understand this law.
While it bans standard AR-15s, it specifically allows AR-15s with "heavy barrels" referred to in MD as HBARs. Also, the barrel can be easily switched out after purchase.
The law simply took a list of 81 specific models of semi-auto rifles and shotguns and moved them from being "regulated longguns" (which required the same hoops and registration as a handgun) and instead made them illegal to purchase. The law also bans any center-fire semi-auto rifles and shotguns with detachable magazines from having certain cosmetic features.
Those cosmetic features have basically no relevance to lethality and can be added after purchase.
So yes, under this law, people can simply purchase other models not listed that do the same thing.
The ridiculous length of most of these bills now is a major part of the problem. They are usually written on K St by lobbying firms and think tanks, then handed to favorable Congress critters to be introduced.
None of them are from DC. They are ALL from other parts of the country. They get ALL of their support from other parts of the country. You just want to wipe out a disenfranchised, majority black city that you know nothing about, because the rest of the country sends people there that you don't like.
Why? DC is solid blue and doesn't even have any political power. DC doesn't have voting representation in Congress or even full home rule. The politicians in power are sent there from the rest of the country.
I definitely get that. I used to fear age more than I do now. Now, I don't really care anymore. Aging just means I am closer to finally being able to sleep for good. Besides, it's not like I am going to reach 90 or anything like that; I just have to hold on till my parents pass and then I can follow them without guilt.
I am in my early 30s now and still barely fit to lead myself...
