Despite being an obvious infringement of the 2nd amendment I wouldn't necessarily be opposed to them either. IF they worked, but they don't.
I'm not sure I can agree. A background check isn't an infringement on rights anymore than a criminal background check is on a job applicant. You might be able to argue that denying a gun to an applicant based on the results of the check infringes on that individual's second amendment rights, but even that is shaky since - in the case of a convicted felon, for example - that individual has given up some of his rights as a result of his choice to commit a crime. Just like an incarcerated individual loses the right to vote, for example (or is supposed to).
Oh, not disputing the efficacy (or lack thereof). Like most laws, they are poorly written by politicians that don't understand the topic, and implemented by inept personnel.
I have a better idea , there should be background checks , in that way if any of the weapons he bought were used in crime,it could be traced back to him. He will soon stop his gunrunning , and there will be lesser crime , lesser workload for the BATF , and smaller government. But you people keep on saying it won't work.
