Plus, locking someone up for committing a murder is punishing a direct harm.

Locking them up for conspiracy to commit a terrorist act would require some affirmative steps towards commission before a person could be incarcerated.

Locking someone up under a theory they could catch something, maybe, at some future point, and may then spread it to a theoretical person who may die, maybe, where the disease is 99.98% survivable isn't comparable to the either of the above examples. Luca is a retard.

HIV is comparable though. And it is a thousand fold more contagious in the gay community. But that's OK for Luca.
