Great idea but... what kind of "tour" of the USA would include Compton CA? Apparently, an "exciting" one, I suppose.
I would suggest a more educational and enjoyable tour would be to go where other "tour"ists go. I wouldn't as a rookie traveler try to reinvent the wheel. For instance, the "real" U.S. is in the small towns, the national parks, the resort areas, etc. If major cities are involved (and they should be) then go (and stay nearby to) where the major attractions are. (They are popular for good reasons -- safety being one of them.) In any event, we have never felt threatened in any large city we have visited -- and that is about 95% of them.
Yes, tourists are an attractive target for mischief but not as much since very few people carry cash anymore. So just go and enjoy yourselves... there are few things that will match the pleasure you will get from your adventure. As they say in New Orleans (which should be at the top of your list): "laissez le bon rouleau de temps" or the current variation: YOLO (You Only Live Once).
Recently, I was given a bit of wisdom that I wish I had known many years ago: "I regret having wasted so much time thinking about things that never happened."
