Common sense tells me that the computer automatically stores images. It's what computers do: temporarily, at least, retain data until either the user permanently deletes the files or storage capacity is exceeded; then oldest files are deleted first. This is a reasonable assumption to make for any computer system.

However, these computers have special plates on them so that the user cannot insert anything into the computer such as a jump drive. The applications do not offer users the option to save any data. The user can't even go to the C-prompt and type in DOS commands.

And we have very strict rules regarding mobile phones and other electronic devices inside the reviewing room. Every officer has to read and sign an agreement to abide by these strict procedures.

I don't know what else TSA can do to ensure images aren't saved, recorded or otherwise retained. I'm assuming that images are temporarily stored simply because that's a fundamental function of any computer, but it's impossible for anyone to view these images.

By the way, the training images are mostly of TSOs and perhaps non-uniformed TSA employees. You can tell because you can see the outline of the epaulets on the majority of the images, and after a while, the body type repeats, which tells me that they used a limited number of people. Only the computerized image of the anomaly is different.
