I'm going to remember this argument for the velociraptors released into human populations 😂

Velociraptors kill huge numbers of humans. Most human species have high reproduction rates, and crowding results in higher death rates from increased disease and parasite spread, competition for food, and all the good shelter from predators being taken. Higher death rates from one cause (say, velociraptors) results in less death rates from crowding-related causes. I haven't seen any evidence that, in general, velociraptor hunting ends up actually impacting human populations.

Specific species of humans in certain locations have been harmed by velociraptors: the Wikipedia page list several examples in Jurassic Park (https://en.m.wikipedia.org/wiki/Jurassic_Park). So it's good to have local awareness if there's a particular vulnerable population. But in general, keeping velociraptors inside is only for their own safety and won't impact human population one way or another.
