Twitter Detects Riots Faster Than Police, Study Says (cnet.com)

A new study by Cardiff University has determined that Twitter can be used to identify dangerous situations up to an hour faster than police reports. From a report: Researchers at Cardiff analyzed 1.6 million tweets relevant to the 2011 London riots. In the town of Enfield, police received reports of disorder an hour and 23 minutes after computer systems could have picked up the same information from Twitter, according to the study. "In this research, we show that online social media are becoming the go-to place to report observations of everyday occurrences -- including social disorder and terrestrial criminal activity," said co-author of the study Pete Burnap.

      The system is failing more and more people each passing year. Racism is still a thing, but it won't do to focus just on that and not the bigger picture. If you look at, for example, the Black Lives Matter protests - obviously, race can play a factor in police misconduct. But the police state problem extends way beyond that. Fixating on the racial aspect of it makes police accountability a more divisive issue than it needs to be. It gives certain white people license to disregard the problem of police brutality altogether. It shifts the focus from abuse of power, to race.

    Riots, like fire, have some pretty easily identified prerequisites.... 1. Groups of people gathering for some reason... 2. Strong emotions around the reason... 3. Strong rhetoric associated with the reason, encouraging people to feel hopeless about affecting some kind of change 4. A faction of people involved who don't mind violence.

      For most people, their ability to change the world is very limited. The key question is whether they can change themselves. But sometimes life has them backed into a corner.

    You could easily imagine a system being developed to track not just currently-happening riots, but the likelihood a riot will happen in the near future. Which area it's likely to happen in. Who is likely to participate.

    Of course, charging people in open court with pre-crime probably won't fly. And a predictive system like this is always going to be a game of probabilities, it might not have the "resolution" to predict individual actions. What you can do is systematically target groups of people for surveillance or manipulation. Not that we aren't already doing that, but now it's more effective.

      I think the intent is more about response time than prevention, though decreased response time would likely help to discourage violent behavior at protests. Perhaps having a police force ready to go nearby could mean 80 fewer minutes of crowd-sourced property damage... though I'd caution against having an "army" of police on display before their response is warranted. Otherwise, it would further add to the "us versus them" mentality that seems to fuel these violent eruptions.

    I was working in the bubs of Seattle during the WTO fun and games and I saw the substantial lag between events and police response. On local live TV I saw the black-block breaking windows and instigating the looting of Starbucks, etc. I also saw on live TV the protesters try and stop the damage/looting while the black-block made themselves scarce. A only after the fact were their police press conferences and riot squad response that only thumped on sweet young hippies in turtle costumes singing save the earth songs. I assume by the time the police hit the protesters, the black block was back at the bar watching the same live TV coverage I was and laughing their heads off. If just one cop would have been watching TV and radioed a couple of beat cops to grab a few of the right juvenile delinquents with the full help and support of the protesters the whole WTO riots would have been prevented. But since the city was crawling with feds/secret service just spoiling to have the local cops crack skulls the whole mess was inevitable. With lessons like these, the idea of some half-baked tarted-up search hit launching the riot squad at the wrong time/people/place does concern me.
