The Council of the City of Philadelphia hereby finds:
(1) The Police Department may from time to time utilize the tapes of video surveillance systems in public places to assist in the investigation of a crime;
(2) Many times, because of overuse and low quality, the tapes are grainy and not useable by law enforcement;
(3) It is the intent of this Section to require the retention of surveillance tapes and that those tapes be of a kind and quality determined by the department through regulation.
