I agree with their logic and would generally agree with its conclusion when applied to other technology, including lock picking tools. As an aside, criminals rarely use those; burglars are more likely to use a crowbar or hammer.

Lock picking tools are not banned in most jurisdictions. In some cases, carrying them in public combined with some other evidence of intent to commit burglary could be a crime, but that's also true of a crowbar, hammer, rock, or anything else that could be used to gain entry.
