Protesters, or at least key organizers, need to be running apps to detect and block IMSI catchers. And everyone not using them needs to put their phones in Faraday bags. So they also need to know how to make Faraday bags from aluminum foil and duct tape.
Good links to walkthroughs on both these would be greatly appreciated. I was at Freddie Gray et al./May Day protest tonight (Friday; see tweets https://twitter.com/douglaslucas/with_replies). There was one point, a key intersection we were marching through halfway into the march, where cell reception inexplicably dropped for a few minutes. There was also, early on, someone in an Austin Police Department hat taking pictures/video from the balcony of a firefighter's station, suggesting that the cops were clued in, which would make sense given the organizing happening on facebook etc., which of course sounds like horrors to crypto snobs but in terms of mobilizing large populations is the only current, repeatedly practiced answer and an effective, if dangerous, one.
