>> They can, but thankfully most people seeking to do us harm (and most people in general) are incompetent. Even the most seasoned computer criminals get careless and make mistakes. People wishing to do us harm don't need computers at all. Just look at the 3 attacks in London in the last few months (Westminster, London Bridge, Finsbury Park). All that is required is a driving license to rent a van and the want to drive it at people at speed. Any person willing to do harm can go out and do it this afternoon without any planning. If we give up our freedoms so that the government can spy more effectively the terrorists will just do more of the above style of attacks.
