Where you are with CISA, I was with CISPA. But CISA extends CISPA so that data collected from providers can be used to further a whole set of unrelated criminal investigations, which blurs the line, from trying to solve a computer security problem to building new investigative tools.
I'm not opposed in principle to new investigative tools, but I don't think debate about them should be avoided by sticking them into cybersecurity bills.
Still: virtually everything organizations like FFTF say about CISA seems to be false, and all you have to do to see how is to read the actual text of the bill.
