Don't be Naive an even think off that ‘this will never happen to me’… yes it could, hopeful not but always be prepared for action if you live in those type of countries!
Are u an permanent resident and authorities wont give u a ‘'gun licence’' leave the place instantly! (except if u have other proper means of defending yourself an is also depending where u live)
Are u on or going on holidays, than the chance that something like this happens is very small an you don't need to worry if your not naive and stick to the global travel rules!
