Don't boycott a country because an easily preventable event occurred!
Numerous threads are saying to boycott vacations to third-world countries like Indonesia. I think the real moral of this story is to NOT attempt to illegally import or export drugs into and out of countries with harsh drug laws. Also put good locks on all of your luggage. This will rule out any involvement of third-parties potentially planting drugs in your luggage. If you don't have drugs in your possession and your luggage is locked tight, you have essentially removed all possibility of being the next Schapelle Corby.
You just have to be very careful going to countries that don't have as rigorous of legal systems as places like Australia and the USA. Also you have to realize you are dealing with people that aren't going to be able to comprehend the English language (or whatever non-native language you speak) as well as you so that will also play a part if you are trying to defend yourself.
Don't demonize an entire country just because someone was either very stupid or extremely unlucky. If it is true that Schapelle and her family weren't really involved, then having good locks on their luggage would have prevented tampering. The fact is that they were either extremely stupid (tried to smuggle drugs) or didn't take the proper measures to insure their luggage's integrity and were very unlucky.
