To decrease the number of sexual crimes it would be enough to legalize prostitution and we could do that now.
In the future rapists and pedophiles will become obsolete thanks to sex robots :)

Whats really dangerous is a society that forces people to compete against each other for survival. If people where all considered equal, as well as given access to everything they need there would be no need for weapons. Of course the only way a society like this would work is if we discontinued the use of money, got rid of our archaic governmental structures, and used scientific methods to reach decisions with the sole goal of human and environmental betterment.
There are thousands of freely available websites and books on the internet all which tell people how to make bombs, guns, poisons and other potential dangerous weapons that could be used for murder, and even domestic terrorism.
Last time I checked, not many people care about that stuff.
hmm... with the shredder option we are getting closer to something like the startrek replicator, at least for stationary items.. didn't make magazine also have cheap 3D printer?
what if people produced weapons? if every person had that kind of production in a household, production would no longer be controlled by corporations or governments, and since no training would be needed and the best design could be shared its seems a little dangerous...
