I believe that you are mistaken. Could they turn over your BitLocker recovery key to the authorities that would then use it to decrypt your HDD that they have already taken from you? Yes.
Are they going to reach out over the internet and take your data? No. They are not going to do that. I follow this stuff really closely. I promise I haven't seen or heard of a capability where they can remotely take data from your machine and turn it over to the government.
