Most of the criminals are not _that_ careful. Among a group of 5, one might forget or have a reason to hide his phone from others because his child is sick and he is expecting a call, for example.

Would it matter though? When my house was burgled, the cops didn’t do a damn thing other than file the report. It’s seemingly not worth their time since “not enough money” was involved. We knew pretty well who did it as well. They only caught up with him once he did some very obvious things at grocery stores.
