California penal code 118 regarding police perjury was passed as a result of an investigation by PoliceAbuse.com in Long Beach California 1989. The law makes it punishable for a police officer to file a false report.
California Penal Code 118.1.
Every peace officer who files any report with the agency
which employs him or her regarding the commission of any crime or any
investigation of any crime, if he or she knowingly and intentionally
makes any statement regarding any material matter in the report
which the officer knows to be false, whether or not the statement is
certified or otherwise expressly reported as true, is guilty of
filing a false report punishable by imprisonment in the county jail
for up to one year, or in the state prison for one, two, or three
years. This section shall not apply to the contents of any statement
which the peace officer attributes in the report to any other person.
The officers in this video wrote a false police report. They stated that they were attacked during this traffic stop. They said that the man thrown into the window pushed himself into the glass after attacking the officers.
They wrote a false report to justify the unwarranted use of force. Both officers were forced to retire. The video and subsequent media attention resulted in a new law in California punishing police officers for writing false reports.
