A better idea
Why don't we have a full lockdown at all prisons and jails in the US, then begin having extremely late term abortions on ALL members of the prisoner population. This would not just reduce the crime rate some over the course of the next 2 decades, but would have a massive reduction in the near term. Over 75% of crime committed today is done so by those with prior criminal records. Empty out the prisons and convert many of them for other uses, such as schools, national labs, etc.
