A few corrections for you, Wise:
New York's crime rate has been steadily dropping ever since the Compstat system was engaged under Commissioner Bratton. Bratton had taken the system from Transit cop Jack Maple and UNDER MAYOR DINKINS had drafted a plan to adapte and apply Compstat citywide. Dinkins lost the following election, but Giuliani kept Bratton on and FALSELY TOOK CREDIT for a system of crime fighting that Bratton devised and Dinkins had approved. When Bratton began to subtly point this out, he was canned.
Your supposition and conjecture about organized crime does NOT change the facts of what Bloomberg pointed out in his public statements. Whether the gunners like it or not, strict gun laws (which existed LONG before Bloomberg came on the scene) are an integral part in lowering crime in NYC.
Bratton was appointed Police Commissioner by Rudolph Giuliani.
Second, some say compstat played a minor role but I believe it played a significant role.
Here are some critics of compstat:
Some, however, such as University of Chicago economist Steven Levitt, have argued that COMPSTAT's crime-reducing effects have been minor [5]. The introduction of COMPSTAT happened alongside:
The training and deployment of around 5,000 new better-educated police officers,
The integration of New York's housing and transit police into the New York Police Department
Police decision-making being devolved to precinct level
The clearing of a backlog of 50,000 unserved warrants
Mayor Giuliani's robust 'zero tolerance' campaign against petty crime and anti-social behavior
Widespread removal of graffiti
Programs that moved over 500,000 people into jobs from welfare at a time of economic buoyancy
Offering housing vouchers to enable poor families to move to better neighborhoods.
Demographic changes including a generation raised in the social welfare systems started in the 1970s and 1980s.
End of the crack epidemic and a shift to a marijuana based drug economy with a larger consumer base and less competition.
Advances in medicine play a role in the declining number of homicides. Better life saving techniques learned in correlation to ongoing modern day military conflicts.
Gentrification, displacement of lower income individuals more likely to commit crimes from gentrifying or gentrified communities.
Another criticism of the COMPSTAT program is that it may discourage officers from taking crime reports, thereby reducing reported crimes, thereby indicating false resolution of community problems.
Similarly, crimes may be reported, but downplayed as less significant, to manipulate statistics to reflect inaccurate improvement of community issues. For example, before a department began using CompStat, 100 assaults were listed as aggravated and 500 were classed as simple assault. Then, under CompStat, if those same statistics were noted for a second year, no improvement is made.
However, if some of the aggravated assaults were downplayed and listed as mere simple assault (25 aggravated and only 450 simple assault), the department and precinct commander would seem to have made progress--albeit only on in reports; regardless of how the assaults were classed on paper for purposes of CompStat, the assaults were aggravated.
Therefore, the community reaps no benefit--except being able to say that statistics show aggravated assault is decreasing. The community's number of aggravated assaults is the same; they are only classified as less serious crimes to appear as though progress is being made.
Manipulating reporting data may also negatively affect personnel and financial disbursement; communities whose improvements (on paper) show they need less resources could lose those resources--and still face the same amount of actual crime on the streets.
Many of these negative effects in the possible weaknesses of the COMPSTAT system were dramatized in HBO's The Wire, as part of an overarching theme of systemic dysfunction in institutions.
Though in your defence? I did find this.
Bratton resigned in 1996 while under investigation by the Corporation Counsel for the propriety of a book deal that he signed while in office as well as accepting multiple unauthorized trips from corporations and individuals. Additionally, there were alleged personal conflicts with Giuliani, partly due to Giuliani's opposition to some of Bratton's reforms and partly due to Giuliani's belief that Bratton was getting more credit for the reduction in crime than Giuliani was
