I think it could be as something as a keyword match, and its either my middle name, or the fact that I have such a common first and last name that matches me to someone, somewhere who may or may not have done something, at some point in time.
It's probably the second one. My little brother used to be on some sort of list that caused us some problems, and he has a very generic American name. This was when he was ~12.
I'm not content to live in a society where the government persistently lies to me and insists upon ruling with "secret" laws and policies.
Aside from the emotional impact, such an asymmetry of information does not foster a democratic process.
