“These additions were made as a result of a suggestion forwarded by a member of the Arlington Heights community. AHPD maintains a ‘Duty to Report’ obligation in our Rules of Conduct. A specific directive requiring an officer to act when they observe a colleague clearly using force beyond that necessary to effect and arrest was not in print,” Pecora said in a n email to CBS 2. “Upon reflection, I felt this addition to our guiding policies will make the organization stronger and allow AHPD to continue as a best practices agency.”
