In the minds of the RIAA and the MPAA, the answer is simple - DRM is far, far more relevant than any small time concern you might have with safety. Freedom to Tinker has had a look at the latest wrangling with the Copyright office over DRM exceptions. There's been a request to allow removal of DRM for software/hardware that deals with critical/life saving equipment, and the helpful folks at the RIAA/MPAA said this:

Furthermore, the claimed beneficial impact of recognition of the exemption -- that it would “provide an incentive for the creation of protection measures that respect the security of consumers’ computers while protecting the interests of the record labels” ([citation to our request]) -- would be fundamentally undermined if copyright owners -- and everyone else -- were left in such serious doubt about which measures were or were not subject to circumvention under the exemption.

Pish tosh, they say - who cares bout a life here, or a life ther? One of the nurses in the ER might be using an exempted device to pirate music!

At this point, we need Buffy or Angel. Clearly, we're dealing with Wolfram and Hart here.
