That differential treatment because of a somewhat higher incidence of particular crimes in an identifiable part of the population may give us some ideas how theses ingenious measures can be applied elsewhere on a wider scale.

It is known that women are more likely to poison someone than men are. So they should not have the right to buy any poison unless accompanied by an adult male.

It is know that men are more likely to drive under the influence of alcohol. So no alcohol should be sold to any male unless in company of a woman with a driver's licence.

It is known that young males are responsible for for much car accidents than corresponds to their percentage in the population. So males should not be allowed to drive a car unless they are 30 years old.

That idea looks as if they have thought about many different possibilities how to deal with the problem and after skipping all sensible ideas they follow the one that (1) will not help (2) is racist and (3) breaks internationally acknowledged human rights.
