I...
1) Shield my screen in public places ( I don't want snoopers reading my emails....) 2) I pay cash most of the time (Helps me save money as the change goes into a change jar never to be spent again) 3) I have multiple cell phones. (One for business, one for personal)
4) I use a proxy to shield my IP address 5) I encrypt my computer and files, I send password protected compressed files. 6) I communicate with people I have never met in video games
7) I sometimes keep track of hackers and learn of vulnerable websites and infrastructures
Seriously though I am not keen on the flier. I think terrorism and extremists work best in fragmented societies. If you live in a small village where everyone knows everyone then the oddball or outcast will naturally be viewed with curiosity and suspicion. However, in towns and cities where you sometimes don't know your neighbor.. this is where a suspicious person can thrive.
Fliers like this encourage you not to trust to your neighbor. It screams. "The guy next to you might be a terrorist!" and encourages you to be distrustful. Its not healthy. It helps propagate the climate of fear. You expect messages like this in a police state not in a supposedly free country.
