Last I looked at this the FCC had issued an exception to the normal rules against intentional interference. The resulting license is based on the idea that the devices will only be used under emergency conditions. Presumably the operators of the devices are having lots of emergencies. I think the problem here is that the federal law against intentional interference is quite definite. So this is the best loophole that the FCC could come up with.
