Have you been to San Francisco? Nobody's getting arrested for that here. No double standard, some laws are enforced more than others. This is about property/violent crimes, not snitching on victimless crimes.
Pot smoking in Cali gets you a citation at best. It's not obvious where she was, and SF's not going track down alleged pot smokers. All the actions mentioned in the article were violent acts and felonies.
No victim making a complaint, not obvious which jurisdiction the action took place, not a crime in all jurisdictions.
The last 3 presidents have publicly admitted to that particular crime. So obviously...
And how many thousands of Americans are incarcerated rate now due to that same crime?
Few, most are incarcerated for possessing large amounts. But in any case, state and federal policy are two different issues.
