A problem many aren't aware of, in an area that shares telecommunications info, two people within that area can be identified by the state sending encrypted messages by seeing when one person sends and another instantly receives a message. It could be easy enough to obscure that I would think by working differing lag times in.

I think it was in the intercept a few years back. I think this is it.
