I'd really like to see the evidence for this. As I mentioned in another comment, from what I've read, possession of lockpicking tools are legal virtually everywhere in the USA, as long as one is not intending to commit a crime with them.
It says it right there on the site! Did you read it??
"Illinois infers from the possession of a key designed for lock bumping an intent to commit a felony." Mississippi says a concealed pick set is prima facie evidence of intent. Similar for Ohio, Nevada, and Virginia. Tennessee code might actually make them illegal outright.
