What&#x27;s exactly the case here? The Feds won&#x27;t grab anyone who&#x27;s PMing some one on Facebook &quot;I&#x27;ll call you&quot; or &quot;Lets talk on the phone&quot;.<p>This is a very specific case where Traders (that either were under suspicion directly or indirectly through suspicious dealing on an investment firm) were intentionally communicating with each other using office provided communications and constantly asking to go offline or to talk through other means.<p>This is nothing more than any other pattern one would find out through exploring any other media, for example one of the ways LEO&#x27;s find illegal activity usually drug related is when by identifying numbers that only receive or make very short calls, this activity is then usually correlated with creating social networks of the phone numbers and what in many cases you get is a binary relationship with phones being used only to receive or make calls.<p>While this might sound suspicious to you, or just interesting after investigating how those criminal networks work through actual investigations criminologists identified this pattern as direct correlation to illegal activity which can be used as supporting evidence to get a wiretap or a search warrant.<p>There are a metric ton of various behavior patterns that might be suspicious and are usually related to some sort of a &quot;illicit&quot; activity if you are looking at some one who&#x27;s leaking information and you have a GPS location on your suspects then some one who&#x27;s driving every 3rd week out to the middle of no where might be your prime suspect, now he can be stargazing, he can be cheating on his wife, or he can be meeting with a contact or making a dead drop.
