Um....,
Every so often we read a post such as yours suggesting posts pointing out problems are some sort of aid and abetting the bad guys.
The reality is any idiot with evil intent in mind can assess the situation at street level and obtain exactly the same information. What is visible to all has to be accepted as "non-classified" information.
Where the folks live, how they get to work, the starting point, ending point, departure times, routes travelled, security personnel, all are quite easy to determine by a simple straight forward recce. The insurgents and criminal gangs are very capable in that regard already.
The problem in these kinds of situations is being able to vary any and all of the above in such a fashion as to be "unpredictable"
The next level if one cannot be "unpredictable" is to be well armed and thus become a "hard" target vice a "soft" target.
I would suggest in Nigeria.....neither of those methods are possible. The Mopo's cannot be relied upon to stand and die in an ex-pats defense. The Insurgents have shown that repeatedly as they appear to have prevailed in all of the attacks to date.
I participated in numerous Protective Services Details over a period of five years thus have an understanding of what methods, procedures, and tactics are used in doing such work. The situation expats are confronted with in Nigeria, particularly Port Harcourt is one I would reccommend to the Protectee that he not expose himself to the risk of ground travel at all and only do travel by helicopter or airplane. Sadly, that adds to the risk element because one has to protect the take off and landing points as well as do the ground escort as well.
At some point the situation will get to the point where all travel becomes too risky and the insurgents will have won.
