I had to register to this site just to say this.
Why am I, a legal United States Citizen who has no criminal history in any of the 50 states or territories, nor a criminal history with the United States government, potentially going to be punished.
If I wish to purchase a semi-automatic rifle because I want to for any reason, I have the legal and inalienable right to do so. If I happen to use that rifle illegally, then I should be punished to the full extent of the law. Any damage I happen to do to life or property is the cost of freedom.
I would like to put this argument another way. PC's exist in the vast majority of American homes. While firearms are not as prevalent, millions of people do own them in America. Some people own several PC's for themselves. This also true of firearms. Almost every one of them is used to commit no crime, but a small faction of people use them to steal identity, publish child pornography, commit fraud, stalk, and a host of other felonies. Likewise, almost every firearm is used to commit no crime, but a tiny fraction of people use them to commit assault, murder, rape, robbery, grand theft auto, and other felonies. Should a person be limited in the choice of computer they can own because it MIGHT be used to commit a crime, might have hardware or software that COULD make it more adept at being used for a crime, or should your computer activity be monitored by authority just because you MIGHT commit a crime with it?
Again, should a person be limited in their choice of firearm because it MIGHT be used to commit a crime, might have attachments that COULD make it more adept at being used for a crime, or should their possessions be inventoried and registered just because they MIGHT be used to commit a crime?
If you answered yes, then I pray you are never risen to a position of power, because you are against the very principles of the United State of America.
