Because, traditionally, and particularly in the USA, money was taken from social services and given to the police.Ok first of all why is money being taken by the police from social services? Why is it a zero sum game in these discussions? Why does the police services have to be defunded? It makes no sense. Crimes still need to be stopped and investigated. Police are still needed. You don’t make society better by not punishing people who break the law. Justice needs to be served. Sure increase services, and look at appropriate sentencing, these are always in review, but why defund the police?
Agree about the social services, but this is being addressed by closing the gap. There have been improvements in some results in the initiative, but more and better results needed. So they are expanding and updating it.
In addition, if the social services are funded appropriately, you won't even need as much money for the police.
