As I see it, there most certainly is a push to criminalize the private ownership of firearms here in the USA. However, it's a battle of attrition and a battle of the mind. If those who control the media can convince the public majority that firearms are inherently evil and that only "official" people should own guns, then the majority public will do the work of banning guns. It's a battle that is being pre-emptively fought by convincing the citizenry that, in a nutshell, the government is inherently good and that we as people can't or shouldn't inherently look after ourselves. In short, we are being brainwashed.
It's happenning on-screen all the time, and not only in the movies. The example of the Rochester news repeatedly reporting on gun murders, without giving any counter examples of gun self-defense, is a fear tactic, used to instill in people the idea that guns are synonymous with murder. The brainwashing is happenning in schools, at both the K-12 levels and the collegiate level. As another poster pointed out, a student who shapes his hand as a gun can now be expelled from school. This sends the definite message that guns are bad and wrong and anyone who pursues them will reap swift, detrimental consequences.
Don't be fooled - there are those who wish to control us, we the people, and are taking decided steps to do so. I believe the UN is a glaring example of how those who wish to control are seeking not merely a country, not soley a continent, but an entire planet, piece by piece. It is a war, it is insidious. It is largely a battle of the mind. Be aware and awake. I know this post sounds dire, but I am firmly convinced of what I've written.
