Sorry, but 11 out of 17 is a huge number to just "wander" off or get left in the bathroom, "separately."

My short answer is, if you want 100% security be prepared to surrender your personal freedoms. And you'll be disappointed. Anybody who tells you different is blowing smoke.

Me, I want my freedom, and I accept the risk. These 11 doofi are resolved to my satisfaction, for reasons I have explained. I'm sorry if you have a lower risk tolerance. That is a problem in a democracy: people with different risk tolerances, and that cannot be solved.
