UK Surveillance Update

NYT: "UK Police Have a Message for Crime Victims: Hand Over Your Private Data".

Three noteworthy points stood out to me:

1) If you don't voluntarily surrender your phone/data, the police may not investigate the crime against you.

2) If the police find incriminating evidence against you for an unrelated activity, they can prosecute you. Because you surrendered your phone "voluntarily".

3) They may keep your phone "for weeks or even months".

OTOH, the police promise to use their power only for good, not for evil. So there's that.
