that actually is not true.....While this is generally true,tools such as lock picks are considered burglary tools and illegal to possess unless you are a licensed locksmith.
in most states, lockpicks are considered "tools".....you can legally carry them anywhere you can carry a hammer or screwdriver.......
they are not considered "burglary tools" unless they are used in the commission of a burglary.....no different than a crowbar or bolt cutters....
i am no licensed and professional locksmith.....but i practice lockpicking as a hobby....and i have never had a problem buying lockpicks from vendors.
