I hate to say it, and maybe anchorage is different...but most off the guns on the street are not coming from robbed houses, though some do.
We have to be careful when saying things like "Doing nothing is no longer acceptable".  Taking action for the sake of "doing something" Is no way to affect real and intelligent change.  Just my two cents.  
For the record, I have no problem with background checks, training, and a 90 day waiting period.  They would at least help curb gun related crimes of passion, deaths of youngsters, and easy legal access for criminals.
Unfortunately as long as tools exist that have to power to destroy, there will be both those that use them for that purpose with no consideration of others, and those that are too stupid to use them responsibly and kill themselves.  We can't legislate intelligence or safety, we have to choose to use our own brains to do so.  To me the real answer is parenting and personal responsibility.
