Wow, that's great, so all the NYPD needs to do is grep through their text message database for "Can you come over?" sent to the same numbers over and over along with their other "code words".

There are secure methods of transmitting data that would not raise the suspicions of police or be trivially greppable.

Very surprised such "sophisticated" criminals let an obvious mistake through a published article. They should have bought a pentest from a reputable firm.
