Jesse Porter, a retired Metropolitan Police Lieutenant, was training a group of police officers on how to use an extendable baton when he pulled out a gun and shot the younger cop.

Support our Mission

Help us build a database of bad cops

For almost 15 years, PINAC News has remained active despite continuous efforts by the government and Big Tech to shut us down by either arresting us for lawful activity or by restricting access to our readers under the pretense that we write about “social issues.”

Since we are forbidden from discussing social issues on social media, we have created forums on our site to allow us to fulfill our mission with as little restriction as possible. We welcome our readers to join our forums and support our mission by either donating, volunteering or both.

Our plan is to build a national database of bad cops obtained from public records maintained by local prosecutors. The goal is to teach our readers how to obtain these lists to ensure we cover every city, county and state in the country.

After all, the government has made it clear it will not police the police so the role falls upon us.

It will be our most ambitious project yet but it can only be done with your help.

But if we succeed, we will be able to keep innocent people out of prison.
