I just want to know what the argument is against expanding background checks. The real, intelligent, researched argument against it, not the "Shall not be infringed upon!!!!11!" argument I usually see.
The argument I always hear is that background checks won't keep criminals from obtaining guns anyway so we shouldn't pass laws that don't do anything except make it harder for good law abiding citizens to protect themselves.
Except it will keep criminals from getting a gun legally. That is the entire point of a background check.
