[GO DAWG GO]

In my law classes in college, "Tort" law was understood as a reasonable person wronging someone criminally or in a civil act if I remember correctly it had to be negligence. I do see a trend in the media that explains negligence as a "mistake".
This man was well aware of his contagious condition and its ability to potentially affect thousands and should be incarcerated in a hospital ward or a government biological facility until he is free of TB. Then do some community service or jail time.

Driving under the influence is more of a mistake than a sober man carelessly exposing people to TB. People with HIV knowingly have unprotected sexual contact with people who are unaware of the condition by no means is a mistake. These acts should be considered felonies.
