Which is why any perceived measure based upon exterior appearance is ineffective as far as airports are concerned. If they can see inside your bag, they really don't have to have any regard whatsoever for what it looks like on the outside.the only problem is that the guys stealing stuff in PR may also be the same guys manning the X-Ray machine.
And it doesn't even have to be a situation where the guy manning the x-ray machine or doing the physical search is doing the stealing. It only has to be a case where he communicates with others, be it by voice, by sign, by marking, or by whatever line of communication allows him/her to let others know what cases/bags/boxes/luggage will be productive. And I doubt that a thief, having been advised a certain case has expensive camera gear, will refuse to steal from it because the case happens to be an old Igloo, looks like any other suitcase or is orange or yellow in color.
