Don’t take anything they can claim is a weapon, even a nail file. Take flags but leave the flag poles at home.
And wear sunglasses (eye scans), don’t speak to friendly strangers, don’t give identity info out, wear a wig or cover hair color. Try not to drive your own car. I was “outed” at a protest of Clinton years ago by a plant. Guy even took my pic. STICK TO TALKING POINTS and DON’T MENTION FR if you go in a group! Be careful, cautious. I’m serious! They’re playing hardball this time.
