I was on board with your post until the last line.

However in the majority of the US it’s perfectly legal to own lock picking tools as long as you’re not using it for malicious intent, there’s only four states in the US that has restrictions on them similar to what you describe, those states are Mississippi where if it’s concealed / you don’t tell them that you have the pick and they find it on their own, you have to provide counter evidence in court of why it wasn’t you; and Nevada, Ohio and Virginia which states you must provide evidence directly countering the claim.

All states have it legal to own and use the tools, it just those four states have increased regulations on the tools that make it harder to defend in court if you’re caught out in public near a crime with them
