The simple slogan of "defund the police" in fact leads to vociferous disagreement among individual activists and organizations about what that means, i.e. whether simply refusing the police military hardware and funding levels, or ending the existence of police outright and replacing them with an unarmed, locally organized neighborhood patrol.
"The war on drugs has been a failure and should end" seems like a similar can of worms. Should the state take the approach of decriminalizing drugs but still aiming to reduce their use by allowing addicts only recourse to medical treatment in special centers? Or should things take a libertarian path and allow citizens to put whatever they want into their own bodies whenever they want?
