Alderman Freeman Bosley Sr. brick theft law

Alderman Freeman Bosley Sr. is proposing a new law to help stop the theft of brick from St. Louis City buildings. This new law, Board Bill # 10, would require City brick yards to close on weekends and require these yards to record each brick transaction on video tape that will be available to police.

Alderman Bosley is right to take action to protect City architecture from such vandalism. But couldn't City Aldermen just require that St. Louis brick can only be sold to City yards by contractors with appropriate St. Louis City business licenses.

Individuals with brick to sell without licenses could be required to document the address from which their brick came. I believe that such a law could greatly limit the City market for stolen brick with out imposing an undue restriction on City businesses.
