I see you responded and I appreciate it. I don't how you can call the G20 a "criminal act". It's a meeting between world leaders. Nothing more. And the police don't detain people for "walking down the street". That's a ridiculous claim.
I deleted your extra thread, thanks for reporting it. Keep asking questions, and rest assured we'll smack around anyone who criticizes you for trying to learn the forum. No one gets it right all the time. I still bungle stuff up. Once again, welcome.
