Morphology of bullet wounds when using police ammunition, type QD-P.E.P

6 years after introduction of the police ammunition QD-P.E.P. (9 mm caliber), 9 bullet wounds are presented from forensic investigations along with the results of experimental shots at pig carcasses. The evaluation reveals the characteristic pattern of such bullet wounds: a skin defect which is almost as large as the caliber and has a sharp-edged border thus looking like it has been punched out; the contusion ring ("abrasion ring") is conspicuously narrow. These findings can be explained by the shape and design of the projectile. In regular police work immediate incapacitation has not always been achieved, depending on the entry location of the bullet. Experimental shots at pig carcasses showed that in the case of shots at extremities, the residual energy of the exiting bullet may be sufficient to generate another penetrating bullet wound.     

Oral fluid testing for cannabis: on-site OraLine IV s.a.t. device versus GC/MS

Saliva or "oral fluid" has been presented as an alternative matrix to document drug use. The non-invasive collection of a saliva sample, which is relatively easy to perform and can be achieved under close supervision, is one of the most important benefits in a driving under the influence situation. Moreover, the presence of Delta9-tetrahydrocannabinol (THC) in oral fluid is a better indication of recent use than when 11-nor-Delta9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) is detected in urine, so there is a higher probability that the subject is experiencing pharmacological effects at the time of sampling. In the first part of the study, 27 drug addicts were tested for the presence of THC using the OraLine IV s.a.t. device to establish the potential of this new on-site DOA detection technique. In parallel, oral fluid was collected with the Intercept DOA Oral Specimen Collection device and tested for THC by gas chromatography mass spectrometry (GC/MS) after methylation for THC (limit of quantification: 1 ng/mL). The OraLine device correctly identified nine saliva specimens positive for cannabis with THC concentrations ranging from 3 to 265 ng/mL, but remained negative in four other samples where low THC concentrations were detected by GC/MS (1-13 ng/mL). One false positive was noted. Secondly, two male subjects were screened in saliva using the OraLine and Intercept devices after consumption of a single cannabis cigarette containing 25mg of THC. Saliva was first tested with the OraLine device and then collected with the Intercept device for GC/MS confirmation. In one subject, the OraLine on-site test was positive for THC for 2 h following drug intake with THC concentrations decreasing from 196 to 16 ng/mL, while the test remained positive for 1.5 h for the second subject (THC concentrations ranging from 199 to 11 ng/mL). These preliminary results obtained with the OraLine IV s.a.t. device indicate more encouraging data for the detection of THC using on-site tests than previous evaluations.     

FEDERAL EMPLOYMENT AND TRAINING POLICY: A VIEW FROM THE LOCAL LEVEL OF GOVERNMENT

To maximize the use of human capital, employment and training resources need to be redirected to meet four objectives: (1) reduce welfare dependency by helping people gain skills for self-sufficiency, (2) prepare a new workforce through better education of youth, (3) retrain dislocated workers, and (4) develop an employment system that links workers and jobs through the coordination of institutions. Suggestions for federal, state, and local initiatives to meet these objectives are spelled out. Particular emphasis is placed upon both a significant revitalization of the federal role in employment and training and a reassessment of traditional approaches.
