Citizens Online Reporting Tool (CORT) is the most well-known place to file a fake report. It's available online and easy to access from any computer.
One must think like an officer in an investigation to file a fake report. A report is full of factual information and someone would have to replicate the exact language an officer uses. The person would also need to know the abbreviations officers use, how to document the scene and the basics of police reporting. Filing a fake police report is also against state and federal laws. It's a 7-year minimum and 20-year maximum imprisonment time for filing a fake police report.
