I don't think it is excactly like that. Don't they like search for more public stuff. Do they actually have instant acces there into private, without any bureucracy even from inside? Hard for me to believe that it takes 10 minutes to go trough all data just like that. And I doubt that there are too many people getting out just like that because some officials can't read their "tweets". Here in finland it seems to so that in 80% of those homicide cases, police has already known who the person is. So I think they are just over excaggerating things. In other hands, in USA there is propably more crime that is "build in system", which make the wrong doers possibly just be some average-joes who were born to poor America.
