Should there be registry for additional serious crimes, not just sex offenses?

A sex offender made a point that he is labeled permanently by his crime while someone who outright kills a child gets out and doesn’t have to register at all.

What do you think? Should there be a registry for heinous or high-risk crimes, sexual or otherwise? Why would the police alert us to a sex offender moving into our neighborhoods and not a convicted drug dealer, batterer or a murderer?

(Correct me if something like this exists already, but I know nothing of it.)
