Yes, it is true, many Hispanics and Vietnamese are among the finest of public spirited citizens ~ they keep that deer heard culled. They'd do a better job but the cops bust them for using firearms in this very populated, urban area.
I have no idea why anyone would wish to propagate more deer.
More deer is the problem, better deer is the objective. The more deer you have, the less range and food, the more inferior/smaller they become.
