Toy Guns don't kill people, people kill people?

Google have been sued for profiting from child porn, generally it seems like a spurious suit. One thing that attracted my attention was that the politician who is backing the lawsuit is also behind a campaign to stop his local shops selling toy guns - I'm not at all sure what this is intended to achieve? It seems to be a widespread phenomenom in America, but the logic seems to be flawed. The problem seems to be that teenage children are going around holding up shopkeepers with 'toy' weapons, but apparently this is not the responsibility of the teenage children in question, or their parents, but a problem with toy manufacturers selling toy guns in the first place. If owning a 'gun' is such a big problem why are they attacking toy manufacturers and not the manufacturers of real guns and the laws which make them so pervasive in American society?
