Government locking
If UK gov gets their mitts on a mechanism to allow remote phone locking, the following will happen.
1. Capita will get the contract to manage it
2. Capita will get hacked and the access stolen, so crims will be able to offer a lock-a-phone-on-demand service
3. UK gov will start locking phones of people they don't like, such as attending certain protests, which also kills the video recording of said protests
