Wearing a t shirt with a big American Flag on it you could walk down the streets of Baghdad. At you own peril of course.
You could walk alone and chance are pretty good you’ll be fine.
You could pay a boy scout and chances are you would be at only slightly lower with essentially only another pair of eyes.
You could hire a private body guard and you would pay quite a bit more but you would be quite safer.
You could hire a team of armed mercenaries and you would be even safer.
Spending more should reduce your risk assuming you hire a good agent. How safe and protected do you want to be? How much guidance and support are you willing to pay to help make the best decision?
The answer is different for everyone and there is no right or wrong answer. Some go it alone and are fine. Some go it alone and get slaughtered. More often then not when I look at someone getting slaughtered in todays market their representation when buying was highly suspect. The funny thing is that often, the highly suspect representation was an agent representing themselves. You all know what they saw about someone that represents themselves in court.
