Based from the places I've visited and lived....
Here's a list of countries that you won't feel safe when you walk alone or in certain times at night:
(More stars means more crime)
1. Malaysia *****
2. Indonesia ****
3. Philippines ****
4. South Korea ****
5. Thailand ***
6. Cambodia ***
7. Pakistan ***
8. India ***
9. Bangladesh ***
That's based on ASIA.... If you want another list of another continent or the thigns happening in each country, let me know... I'll be more than glad to list it here.

Anyway, tips for travellers... Just use common sense. It's that simple.
I've been all the way to Nepal & Iceland but have been pretty safe on my travels (Note: It's usually the authorities that makes a bad image of the country)
Happy holidays!

Those look like Christmas lights hehe!
