Suicide no... but I do not think people would respond very kindly to it. They may not allow you in the shops maybe through stuff at you but nothing too bad.
1.That won't cause suicide
2.If you yell 'FREE TIBET' out loud then you get arrested I mean serious now and no it is not so good idea because did you hear about that story on the news about this man climbed up a pole and a flag free tibet and he up the pole radioed to the man below and was saying 'If I shout out free tibet then all hell will broke lose and I then stay up here then coming to end this tibet war.
There you are then opition 2 take my advice or someone else's it's up to you you decide
