Re: Janeway's Decision to Kill Tuvix
When we do something, do we always know every single possible risk? I suspect not, as sometimes something unforseen can occur that the creators/inventors never even thought could happen.
At the time of the episode, transporters had been in use well over one hundred years.
From Memory Beta
"By the 24th century, most space-faring civilizations of the Alpha and Beta Quadrants employed transporter technology for short-range transport of personnel and equipment. There were many advantages to utilizing transporters.
Traveling by transporter was essentially instantaneous and an individual's sense of time while transporting was effectively non-existent. Benjamin Sisko and Harry Kim, while training at Starfleet Academy in San Francisco, frequently transported to New Orleans and South Carolina, respectively, to see their parents. (DS9: "Explorers"; VOY: "Non Sequitur")"
So yes I do think that all the people in the Federation knew about transporters and in general come to expect to be moved from one point to another safely. I am also relatively sure that Star Fleet had a policy of protecting the safety and the individual rights of the people that chose to serve. You wouldn't get too many volunteers if you didn't.
