That site is wrong, lock picking tools in all those States are still legal to possess for non-criminal purposes same as all the other states. They just consider possession of such tools to be prima facie evidence that you have criminal intent. Prima facie evidence is basically evidence that if not disproved by the defense is by law sufficient to convict.

So that means it's still legal to possess such tools in those states. But if prosecuted for criminal possession you basically lose the presumption of innocence and must prove you had no criminal intent rather than the state being required to prove that you did.
