the use <str<strong>on</strong>g>of</str<strong>on</strong>g> low-intensity supervisi<strong>on</strong> with the lowest-level <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders. <str<strong>on</strong>g>The</str<strong>on</strong>g>se clients need<br />
no more than the minimum input <str<strong>on</strong>g>of</str<strong>on</strong>g> resources necessary to ensure that they are not ‘false<br />
positives’ and have the tools needed to rebuild their lives.<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g> strength <str<strong>on</strong>g>of</str<strong>on</strong>g> the<br />
Philadelphia predicti<strong>on</strong> model allows us to say with some c<strong>on</strong>fidence that we can identify<br />
a large proporti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders who fall into this category. This leaves the agency much<br />
better equipped to deal with the ‘power few’ highest-risk <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders.<br />
Of course, no assessment or validati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> a statistical predicti<strong>on</strong> model can bring<br />
complete peace <str<strong>on</strong>g>of</str<strong>on</strong>g> mind in terms <str<strong>on</strong>g>of</str<strong>on</strong>g> guaranteeing the <str<strong>on</strong>g>of</str<strong>on</strong>g>fender management approach that<br />
best assures public safety, just as the model itself cannot indicate exactly who will turn<br />
out to be low or high risk. We c<strong>on</strong>clude that the Philadelphia model is successful in<br />
classifying <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders by risk, but 30 per cent <str<strong>on</strong>g>of</str<strong>on</strong>g> the predicted low risk <str<strong>on</strong>g>of</str<strong>on</strong>g>fenders in our<br />
sample had committed at least <strong>on</strong>e <str<strong>on</strong>g>of</str<strong>on</strong>g> the most serious <str<strong>on</strong>g>of</str<strong>on</strong>g>fenses at some point in their<br />
adult <str<strong>on</strong>g>of</str<strong>on</strong>g>fending careers.<br />
Some <str<strong>on</strong>g>of</str<strong>on</strong>g> that group do not react as well to low-intensity<br />
supervisi<strong>on</strong> as their counterparts with no history <str<strong>on</strong>g>of</str<strong>on</strong>g> serious <str<strong>on</strong>g>of</str<strong>on</strong>g>fending, and we do not yet<br />
know why, or if their performance will worsen as more data are collected. We return to<br />
c<strong>on</strong>siderati<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> Grove and Meehl’s (1996) comment: “<str<strong>on</strong>g>The</str<strong>on</strong>g> statistics furnish us with the<br />
probabilities so far as anything can” (p. 306). Any attempt to routinize criminal justice<br />
decisi<strong>on</strong> making will necessarily be c<strong>on</strong>cerned with averages, but it seems that<br />
Philadelphia’s probati<strong>on</strong> agency has developed a successful model that can help to<br />
allocate resources where they are needed most, and can easily be adapted for use<br />
elsewhere based <strong>on</strong> the informati<strong>on</strong> available to the specific agency.<br />
