There is a fairly standard Science Fiction plot device where certain events are removed from memory with a simple injection. In the context of the story, we just accept this and wait to see what happens next. We accept many things in stories that couldn't really happen. But then again...
OK, so it's not quite the erasing of memory, but it's not Science Fiction, either.
Doctors are investigating the use of drugs to lessen the force of traumatic memories. This is, of course, a controversial idea as we are, to a large degree, the sum of our experiences.
I am, generally speaking, in favor of expanding human understanding and opposed to allowing fear to rule science, but I must say that it would seem that this is an area of research where we need to tread very carefully.
