Effective enforcement of the competition laws requires public support. Whether you are a District procurement officer, private businessperson, or simply a consumer, if you encounter business behavior that appears to violate the law, do not hesitate to inform the enforcement authorities of your suspicions. That is often the only way violations can be uncovered, and failing to uncover and punish violations not only harms consumers and taxpayers but also the vast majority of honest businesspeople who scrupulously observe the antitrust laws.
