I personally support decriminalization but given the greater context I completely understand why the public perception of this program was utter failure.
Right now a very small minority of repeat offenders are acting with impunity. The courts fail to deny these individuals bail, thus substantiating the accusations of "catch and release".
The fact is that drugs damage peoples mind to the point that they will steal/do whatever they must in order to fund their addiction. And the courts just keep letting them walk free.
