Another political reason for GSM Pro not to exist in the UK is it would have scotched at birth the failed commercial Dolphin Tetra system. So by not enabling GSM Pro in the UK not only have we prevented the security services from a cheap effective system but also commercial users too And ordinary GSM users have lost out as well as obviously they would have had back spots filled in their coverage with gov backed extra cells on emergency service advice.
