This is a parallel topic to firearms - mostly because its a situation whereby we are unarmed as we are traveling outside of the United States. In our home states, we are familiar with our States carry laws. But when you are outside the United States and not able to carry a firearm, what steps do you take to insure your safety? In my work on the Federal level, I cannot go into detail on what exactly I do, but I can give you some baseline safety tips on how to maintain security awareness and not make yourself a target.
BEFORE you leave: Contact the State Department and see if there are any security advisories in the country that you are planning travel too. Make sure that you know exactly where the US Embassy is in the country you’re headed to. Call that embassy and ask them if they are aware of any local concerns. Tell them where you are staying and how many are in your group and the dates of your travel there.
WHEN you arrive: Be sure not to wear anything that identifies you as an American. Something that says “USA” might as well be spelled T-A-R-G-E-T. Understand that you do not have a Second Amendment right when you are not on US soil. Do not take the same route to your hotel or eat at the same restaurant two days in a row. Be aware if the same car passes you more than once or a person is “eyeing you” or monitoring you. Have a duress word known to the members of your group that can be casually used to alert the group to a problem. (I will usually create a fictional person and say that we need to meet up with that person as a duress code)
Enjoyable business trips and relaxing vacations are due to planning. No one likes to have the unpleasant “Security Conversation.” But if you PLAN for this element and understand what to do, the better and ultimately SAFER the trip will be. There is ALWAYS a chance on any trip that something will go sideways on you.
The time to prepare for that is not when the emergency is happening. That’s when you will PANICK, rather than RESPOND to the emergency. If you have already PLANNED what to do, if the emergency happens, your brain will automatically engage into what you have planned.
