Physiqueflex saidI think this act addresses a problem that the gun owning community ignores, that all guns that were obtained illegally or used illegally were legal guns until that point in time. It is what happened at that point in time that this addresses.
There are hundreds of thousands of guns stolen every year, but not one peep from the overwhelming number of gun owners who aren't irresponsible and do the right things with their weapons.
If a gun is stolen and used in the commission of a crime, isn't it possible the the original owner has some responsibility for the crime? If a gun is purchased illegally and used in the commission of a crime, doesn't the seller have some culpability?
A lot of it depends on circumstances.
To use the automobile analogy -- if someone steals your car and uses it in a drive-by shooting, are you responsible? Should your insurance pay for the injuries or pay compensation for the deaths resulting from the incident. Maybe. If you left the keys in the car, or left it unattended and engine running at the curb, there's a good argument that you were negligent.
If someone didn't secure a gun properly, left it accessible to unauthorized people, or allowed a known irrational or irresponsible person to use it, then the argument can be made that the owner bears some culpability.
It seems that the left has the attitude that mere possession of a firearm, no matter how safely stored, is an irresponsible act and should be subject to punitive measures.
The public at large seems to have a more tolerant attitude toward guns. National polls are showing a trend toward more accepting attitudes toward firearms ownership and usage. Gun dealers and manufacturers have had record years of production and sales. Accessory sales are higher. Range owners and firearms trainers have seen many new shooters come in for practice and training.

Mainstream American attitudes toward guns seem incomprehensible to Brits and Europeans. Liberals on the east coast and in the larger US cities seem to have a similar disconnect.
