I'm amazed, given what's happened in DC, 9/11, the snipers, terrorist threats that one of the plaintiffs is a Special Police Officer at Thurgood Marshall Justice Center, armed on the job but denied permission to have a handgun at home.
Only to a point. Congress gave up much of their power over DC years ago with "home rule". Many years before that, they gave up even more of their power to the federal courts. If some judge says the law is out, there is nobody in this congress with the stones to tell him it stays.
Remember congress didnt pass D.C.s gun laws it was the residents. The same people who elected Marion Barry over and over voted in the people who passed these laws. Congress did nothing about it when they passed these laws. They will do nothing if the laws are thrown out.
By the same token, there is nobody in this congress with the stones to tell the judge no if some judge goes the other way and says the law stays. The balance of power the founders set up has been gone for many years. We last had a real balance of powers when Andy Jackson was president.
The good news is we might get a judge who read the Constitution once or twice and rules in our favor. But those judges are few and far between. If they werent we wouldnt have most of the laws we live under today.
