Sure, you’d kill Baby Hitler, but what about other famous babies? Who would you take out?

Sounds like one of Tony Blair's dystopian ideas from 2007:
[quote]A Downing Street document said the checks could take place at important stages in a child's life, such as the move from primary to secondary school. It said the Government may "establish universal checks throughout a child's development to help service providers to identify those most at risk of offending".

The paper adds: "These checks should piggyback on existing contact points such as the transition to secondary schools."[/quote]

Once you start with such things no one will be safe from condemnation.
