Exclusive: Fake cellphone tower may have surveilled protesters at Portland ICE facility

SAN analyzed cellular signals outside the #Portland ICE facility last weekend as President Donald Trump attempted to deploy National Guard troops to a city he described as “war-ravaged.”

SAN analyzed signals using a device called Marlin. The scans detected over half a dozen IMSI-exposure ratios above 10%, and three separate 18% spikes in just a one-hour window — significantly higher than what the Marlin developers ever registered under normal conditions.

Away from the building, that percentage began to drop. At a hotel 3/10s of a mile away, percentages hovered around 1% to 4% with occasional spikes as high as 9% over a roughly two-hour period.

In SAN’s extensive use of #Marlin over the past four months, the only other time an IMSI-exposure ratio was detected was outside an #ICE facility in Washington state.
