Randomized Controlled Trial (RCT) / Randomized Field Experiment

Refers to an experimental research design in which participants are randomly assigned to a treatment or a control group. Most social scientists consider random assignment to lead to the highest level of confidence that observed effects are the result of the program and not other variables.

Law Enforcement

Local, state, tribal, and federal law enforcement officers perform a number of prevention and enforcement functions and duties across the United States (U.S.). Examples of these include criminal investigation, patrol and call response, community-based crime prevention, corrections and detention supervision, court operations, and security or protection.
