I would suggest they are somewhat unjustified.
If an evaluation is done by a drug recognition expert, that evaluation must be reviewed by an instructor. Every evaluation the person does is put into a log. We're now working on an electronic log that will be done via the Internet, so I can access any evaluation anytime. The instructors review it to make sure the protocol is done correctly and the fines are correct—and these are things they must do to remain in the program. As a DRE, we must be recertified every two years.
If a DRE doesn't comply with the program, or they're consistently doing things that would bring the program into disrepute, then they're decertified and their supervisor will be notified of the fact that they've been removed from the program. I expect there would be some kind of sanction taken against that individual, because they're putting not only the program in disrepute, but also the agency they're working for.
So I just don't see that being an issue.
