approach. we do have some ability to mine that data. i mean goodness sake, if i go online looking for hiking boots, the next day all my accounts, i m getting offers for hiking boots all over the place. it s as simple as that? it s the application that is applied to a specific task to find out what people are saying, where they re saying it and how virulent it is. even so, even if you get to that point, the question is now what. the person can spew the most vile, racist, hateful rhetoric. until they say tomorrow i m going to take a weapon and do the following, it s not action al. so that s the problem. is there a no-gun list we can come up with for psychotic people? sure there is but there has to be steps taken. and there s a difference between hate speech and a hate crime. hate speech is protected for the most part and that s the challenge for law enforcement. as you re going out to data mine things on social media, how do you bifurcate the two? one is an action, one is words.
