Violent Crime In MarylandAnd Selected Jurisdictions

• This Material Represents an Interim Report Based on Data Obtained from the Maryland State Police.The State Police Population Estimates for Baltimore City Differ Significantly (Approximately 6%) from that of the US Census Bureau. See the two Web Sites:www.census.gov/population/estimates/metro-city/scts96/sc96t_MD.txt

• www.census.gov/population/estimates/county/co-97-1/97C1_24.txt

This Analysis Uses the US Census Bureau Estimates.

• This Report is Intended to Raise Questions and Not Give Answers.A Complete Analysis Would Require Effort to Examine Law Enforcement Effectiveness in Prince George’s and Montgomery Counties and in Baltimore City.Resource Allocation to Law Enforcement Should Also Be Studied.

• The Analysis was Made Possible Because of the Work Performed by the Maryland Citizens Defense League in Collecting Data from the Maryland State Police.

Maryland Crime Observations

• The Graphs Show Normalized Crime DataNormalization Means Yearly Data is Displayed as Percent Relative to the Average of the Rates Over the Period Shown.The Average Values, Taken Over the 23 Year Period Shown, Appear on the Plot as Text Inserted Near Their Rate Data.The Normalization Permits Common Trends to be Observed for Crime Data that Have Different Scales, Provides a Uniform Basis of Comparison, and Permits Common Trends to Be Seen Easily.

• It Scales Yearly Deviations from the 23 Year Average By a Weight Indicating the Importance Society Places on the Type of Crime. (e.g. Murders Are More Significant Than Property Crime So the Weight 1/AveMR is larger than 1/AvePT)

• Violent Crime Total Rate has Increased Since 1988 and, in the Early 1990’s, was 10% to 20% Above Its Average.

• Property Crime Appears to be Stable to Slightly Higher than Average Over the Past 10 Years

• Although the Murder Rate Appears to be Stable, in the Early 1990’s the Montgomery County Violent Total Crime Index and Aggravated Assault Index Were 10+% Above Their Averages.

• The Fluctuations in the Murder Rate is to be Expected with the Small Numbers Involved -- No Statistical Significance Can Attach to the Year to Year Changes.

• Montgomery County Violent Crime Rate Is Well Below that of Maryland State as a Whole.Montgomery County Murder Rate and Aggravated Assault Rates Average Approximately 40% to 50% of the National Rates and 30% of the Maryland Rates.

Montgomery County Does Far Better than Nearby PG County and Baltimore City.

• Why is Montgomery County so Relatively Safe?

Baltimore City vs. Maryland(Continued)

• Since Baltimore City Now Has 1/7 th (Approximately) the Population of Maryland, the Ratios Could not Exceed 7 Even if All the Crime Happened in Baltimore City and None Elsewhere.

The Ratio of Murder Rates Is Nearly 5 Indicating that Most of Maryland Murders Happen In Baltimore City.The Increase in Maryland Crime Rates Results from Baltimore City.

• Trends in Baltimore City Are Masked by Decrease in PopulationBaltimore City Averages 56% of Maryland’s Murders Over 23 Years, But Population Share Has Declined from 21% to 13%.Looking Only at Crime Totals Hides How Bad Conditions Have Become.

• Actual Crime Growth is Shown By Rate Comparison of “Baltimore City vs Maryland” Chart.

The Trend Lines Drawn on the Graph Are Parallel and Indicate a General Behavior Which Should Be Addressed by Law Enforcement.

• Are Maryland State and Baltimore City Leaders Applying Resources Where Crime Is Happening? Shouldn’t They Be?

Baltimore City vs. Maryland(Concluded)

• Maryland Crime Rates are being Driven by Baltimore City• The Local Nature of Baltimore City Crime Problems Insure State

Wide Solutions Will Not Be as Productive as Local Solutions.Adding Police Officers State Wide in Maryland Would Waste Resources -- They Should be Added to Baltimore City.

The Problems of Baltimore City Violent Crime are Not “Gun Control” -- They have the Same Controls as “Safe” Montgomery County.

• Baltimore City Violent Crime Will Not Be Solved Until the Source of the Local Problems Is Identified.Inadequate or Misallocated Crime Fighting Resources?

Political Leaders Indifferent to Law Enforcement Needs of Economically Disadvantaged Population?

Corrupt Local Government Officials (Revolving Door Judges)?

• PG County Has Similar Crime Problems Although Less Severe Than Baltimore City.

Are Maryland Politicians Guilty of Criminal Neglect for Treatment of Crime

in Baltimore City and PG County?• Baltimore City, Montgomery County, and PG County Each has

Approximately 1/7 th the Population of Maryland (700,000 vice 5,000,000).

• PG County and Baltimore City Have Averaged Between 3.4 and 8.3 Times As Much Violent Crime As Montgomery County Since 1975.

• Baltimore City Is Trending to Even Higher Factors of Violent Crime When Compared to the Whole of Maryland.

• Public Safety in Maryland is Almost Entirely a Problem Particular to Baltimore City and PG County.With a Combined Population of About 28% of Maryland They Have Nearly 80% of Murders and 58% of the Violent Crimes.

• Attacking Violent Crime in Maryland Cannot Succeed Without Increasing Law Enforcement Resources/Effectiveness in Baltimore City and PG County.
