Millions of cars have been spotted by license plate scanners, and logged into massive government databases for several years now. Also, they make the information available to any law enforcement agency that makes a request. Details are limited, and its unclear how many detentions, arrests, or convictions have resulted from the program.
Lee County has its own license plate scanning program, as we discussed in Big Brother post a while back. I suspect Collier County does as well, due to the nature of some police stops I have seen, but I haven’t seen any public information about it: that remains my suspicion. Meanwhile, only a small percentage of deputies have cameras in their cars.
