In political news 75 year old Buffalo protestor Martin Gugino has been generating controversy due to a video of him being pushed to the ground by a police officer, then subsequently lying motionless while bleeding from the head and being ignored by other officers.
Recently US president Donald Trump tweeted about a video news report by "One America News" (OAN) indicating that Gugino may have been trying to scan police with a "capture scanner". Whilst talking about the capture scanner they show an image of an RTL-SDR dongle and Android phone running the SDR Touch software. OAN go on to say that these capture scanners are designed to "skim microphones" in order to capture police communications, and are a tool commonly used by Antifa. Credit to @hackerfantastic for initially tweeting about the RTL-SDR being featured in the video.
Trump's tweet reads "Buffalo protester shoved by Police could be an ANTIFA provocateur. 75 year old Martin Gugino was pushed away after appearing to scan police communications in order to black out the equipment @OANN
I watched, he fell harder than was pushed. Was aiming scanner. Could be a set up?".
We're not entirely sure where this theory from OAN came from as there is no need to get so close in order to listen to police radio communications, since if unencrypted, they can be listened to from anywhere in the city. It's also unclear as to what microphones police would be using, and how these could be "skimmed" with an RTL-SDR. As for blacking out the equipment, an RTL-SDR cannot transmit so it would be impossible to use to jam the radios. An illegal jammer could be used after scanning, but police frequencies are already well known anyway, and there would be no need to scan for them so close even if low power comm links were used.
The video also shows that he appears to be filming police badge numbers with his phone before he was pushed, so it is unlikely that he was using an RTL-SDR and running SDR Touch at the same time as the camera app. No cables, antenna or dongle can be seen in the video either.
In the past we have seen a Slovenian researcher almost jailed for performing University research with an RTL-SDR, and a UN expert arrested for possessing an RTL-SDR in Tunisia. So this is a timely reminder to be careful as police and media do not always understand what an SDR is.
