I'm guessing it is similar to my department. Low Bid. LAPD has, to my knowledge, over the years had their shields (series 5 and 6) made by:
- L.A. Stamp and Stationary
- LARSCO
- Sun
- Entenmann-Rovin
- Blackington
and others.
When a city / county contract expires, it is usually put out again as an RFP (Request For Proposal) and then an RFB (Request For Bid) and the purchasing department awards the bid. Interestingly, even though the specs are supposedly identical, the actual produced badges are different enough that they can be used as evidence. One cop was dissing LAPD on videos with his face covered and a piece of tape over the badge number. They were able to forensically determine which company made the badge (from the film) and narrow down the personnel issued that "run" of badges. Further investigation narrowed down the possible culprits and eventually the offending cop was caught and disciplined.
