The S.T.O.P. Plate program is offered as a service by the UCPD, through the CSO Programs, as a crime reduction initiative. Laptop theft, and the theft of other highly portable and easily re-sellable electronic items, is one of the most persistent crime threats on campus. By encouraging the use of theft deterrent systems like the S.T.O.P. program, UCPD hopes to reduce the number of thefts on campus and discourage opportunistic laptop thieves.
