We should simply lock everyone up, who could become a bike thief. If you have hands and legs, i personally find that very suspicious.
The problem is, that there is a strong retalitation instinct in humanity, to enforce group norms.That worked well in villages, but if allowed to be lived out produces ridiculous amounts of locked up people.
Whats even more disturbing is, how those locked up people are not allowed to be a productive part in society. They get hamster-wheelian-jobs in the prison industry, instead of continuing with there real jobs.
