I think one will find those statistics are based primarily on criminal prosecutions rather than actual crime numbers committed. Today so many liberal DA's and AG's have higher political aspirations and they are very reluctant to take on any case where they might lose. They want all checks under the 'W' column when the time comes. They often themselves have supported much less laws and penalties they have a way to evade even having to bring charges.
Remember, liars can figure ... figures can lie!!!! And statistics can be written to prove almost anything. Anyone with one eye can see that CRIME has not gone down virtually anywhere to any degree. And those who believe it needs to take a second and realistic look.
Sorry, I'm still trying to be respectful, but this assertion on it's face is preposterous!!!!!!!!
