Charlie Eppes:
There's something else that has to be considered.

Don Eppes:
Like what?

Charlie Eppes:
Heisenberg's uncertainty principle. Heisenberg noted that the act of observation will effect the observed; in other words, when you watch something, you change it, and uh, uh, for example, an electron, you know, you can't really measure it without bumping into it in some small way. Any physical act of observation requires interaction with a form of energy, like light, and that will change the nature of the electron, its path of travel.

Don Eppes:
Hold on. You know I got, like, a C in physics, so just take me through how this relates to the case.

Charlie Eppes:
Don, you've observed the robbers. They know it. That will change their actions.
