At the core of this is the old, philosophical question of, "Is it better to let one hundred criminals go free if it means not wrongfully convicting one innocent man?"
Considering that we are talking about bail (meaning 1-2 weeks in jail, not a lifetime in prison) and we have justice systems that are right 80-90% of the time, I lean towards the more pragmatic statistical approach.
The "internationally recognized human right" thing seems like a thought terminating cliche, not sure why that should be the end of the discussion.
