I saw on the same program recently, NCIS, where Abby was downloading from the black box on a vehicle with a scan tool. Well, I worked for OTC, which produced scan tools as well as other automotive tools. The tool she was using was one of our products, an Actron code reader. The model that I saw, was a very basic unit that barely read engine codes. No ABS, no air bag, or any other major codes. And sure not the black box. The unit shown was about a $50.00-75.00 item at most. To read the black box, will cost at least $2000.00 minimum. But, that was not a serious offense, that could cause a lot trouble with weirdos.
Other than that, I love NCIS. But, I am getting real tired of Hawaii five-O, with all the fake. I think that is part of the problem with some of the situations in the world lately.
