The Texas Unlawful Use of Criminal Instrument or Mechanical Security Device law gives police the right to arrest you if they believe you possessed lockpicking tools or any other tools designed for use in the commission of crimes if you intended to use those criminal instruments to commit crimes, or if you sell, install, or set up any such device knowing that it was something that was intended to be used in criminal activity.

This is a specific intent crime, meaning that it is not illegal to merely possess these tools – it is illegal to possess them only if you have the intent to do something criminal with them. The legislature defined both “criminal instruments” and “mechanical security devices,” but the definitions are quite broad.
