These guys violated the provisions of their visas. Open and shut case.
That isn't the issue in dispute. The issue is whether or not there was an ulterior motive for 11 of them to wander off to various parts of the U.S. You seem to think it was an innocent mistake by 11 different Egyptians. That's your choice. I'd like to know a little more about the whole situation. I'd rather err on the side of security, than assume this was nothing more than ignorant foreigners being "lost."
