FBI/DHS overflights in the US
Interesting Buzzfeed article on this with lots of FR24 trails etc. Worth a read.
Someone is racking up a lot of hours in Cessnas :-)

Nemrytter - I did think that about the more rural trails from the West coast - some of the orbits were over very specific locations - not sure what sort of signals based intel the "bad guys" could get from that....

HT - Signals based intel, in WWII a lot of intel was gained from traffic volumes etc even when signals weren't decrypted. Historic or real-time FR24 data could be used to check if you are being watched - I'd guess this risk only applies to rural locations or very time/location specific info in an urban area.
Can't they turn Mode S off or is it mandatory in that airspace?

You underestimate the ingenuity of radio enthusiasts. Multilateration of Mode-C replies would give information similar to that of Mode-S or ADS-B. I don't think turning off transponders in a crowded airspace would be feasible.
Or, so they tell me...

Interesting article. A basically good, factual article about one "tool" that law enforcement has at its disposal and evidence of its use. I'm disappointed about two "issues" that underlay the reporting.
The vauge conspiricy theory of "big brother is watching" is an unnecessary "slant" thrown in for certain readership diminishes the credibility of the reporter for me.
The fact that one "tool" of law enforcement is exposed (even though it hasn't really been hidden) DOES give the criminal element a heads up. I prefer that dumb criminals stay dumb and smart criminals be ignorant.

When I worked as a fueler at the local airport, the FBI had(and still has) a hangar with a fleet of Cessnas, the biggest being a C-208. This article is very accurate about the equipment. We'd fuel them up during the week and off they went to spy, but the weekends were for football and beer, so no flying then. The pilots were always friendly and would get chatty and let us wide eyed fuel boys in on their little secret airplanes. Now I'm a bit older, a bit more grizzled and cynical. My work allows me a small window into that world and you'd be surpised of all the law enforcement equipent in our skies. Local small police and sheriff departments run Cessnas with some amazing equipment onboard in addition to the helicopters, major cities like L.A. have huge fleets and have no issue with hovering right up to your window and destroy your night with that billion watt lamp(happened to me more than once). Federal level has Airvans, tricked out Blackhawks, Bell 412s, you name it.

Not unless you've blocked your tail number.
However, anyone with a $30 ADS-B receiver can always decode the raw ADS-B stream, get the ICAO addresses, then perform tail number mapping.
With 978 MHz ADS-B (UAT) there is an anonymity function for VFR aircraft but that won't prevent enthusiasts / journalists / bad guys from noticing flight patterns such as the ones described here.
