This is already the law in many places. This is an article about Canada but, for example California Model Penal Code 466 says that: Every person having upon him or her in his or her possession a picklock, crow, keybit, crowbar, screwdriver, vise grip pliers, water-pump pliers, slidehammer, slim jim, tension bar, lock pick gun, tubular lock pick, bump key, floor-safe door puller, master key, ceramic or porcelain spark plug chips or pieces, or other instrument or tool with intent feloniously to break or enter... is guilty of a misdemeanor. Basically, if you are carrying anything that will be used for breaking and entering, with the intent of breaking or entering, that also is a crime.
