Will we (the U.S.) ever be able to have a constructive dialogue about commonsense gun legislation?

The incidents keep coming. How many times does this have to happen before we can have a constructive dialogue about common sense gun control legislation? Stop screaming that controls = infringing on the right to own guns! Everyone has to take a class, pass a test, carry insurance, have liability insurance and pay taxes on cars; shouldn’t the responsibility of owning a WEAPON be taken just as seriously?

(On a tangent, how is a “well armed militia” the same thing as a totally unregulated, undisciplined and uncontrolled public?)

Will it ever happen?
