John McAfee serves up many (speculative) points of interest:
The most powerful tool a traveler can possess is a Press card. It will allow you to completely bypass the “documentation” process if you have limited time or limited funds and don’t want to deal with it. I have dozens stashed in all my vehicles, in my wallet, in my pockets, in my boats.
I am paranoid about being caught without one when I need one. They have magical properties if the correct incantations are spoken while producing them. A sample incantation at a police checkpoint (this will work in any Third World country):
“Hi, I’m really glad to see you.” (produce the press card at this point). I’m doing a story on Police corruption in (fill in country name) and I would love to get a statement from an honest police officer for the story. It’s for a newspaper in the U.S. Would you be willing to go on record for the piece?” You can add or subtract magic words according to the situation. Don’t worry about having to actually interview the officer. No sane police person would talk to a reporter about perceived corruption while at the task of being perceived to be corrupt. He will politely decline and quickly wave you through. If you do find the rare idiot officer who wants to talk, ask a few pointed questions about his superiors and it will quickly awaken his sensibilities. He will send you on your way.
The press card is powerful, but has risks and limitations. Do not attempt this magic, for example, at a Federale checkpoint in Mexico on a desolate road late at night. You will merely create additional, and unpleasant work for the person assigned to dig the hole where they intend to place you.
Here is another bit:
Smile and, if possible, joke. Say something like: “I’d like to stay and chat but I’m in a hurry to meet a girl. Her husband will be back soon.” This will go a long way toward creating a shared communion with the officers and will elicit a shared-experience type of sympathy.
The advice is interesting throughout, but caveat emptor, please.
For the pointer I thank Patrick.
