This is from "Artificial Intelligence For Dummies".
Some research will require you to be able to identify persons used within a dataset. Going out and grabbing Personally Identifiable Information (PII) isn’t a good way to gather data. For one thing, you can’t be sure that the information is either complete or correct, so any analysis you perform is suspect. For another thing, you could encounter the messy and costly consequences of legal actions.
I wonder what'swhat the meaning of 'going out and grabbing' is here.
Does it mean 'obtaining something by unethical or illegal means'?
