Lang genuinly feared for his life and believed that the "corrupt Fresno cops" were out to get him as further demonstrated by other posts:

According to one of Lang's diary entries, he discovered a license plate scanning scam where Fresno cops would scan license plates at Retail Store parking lots (Save Mart, Von’s, HomeDepot, etc.) in lower income neighborhoods. After collecting hits of violations they then would pull the unsuspecting drivers over a few blocks away from the store location in a marked police vehicle claiming they simply came across their vehicle through routine driving patrols. After exposing these corrupt activities on to social media and comments on news outlets, Lang quickly finds himself targeted by local law enforcement beginning to intimidate and harrass him outside his home:

John has documented the harrassment on his youtube channel:

What are your thoughts? Do you think this is evidence enough for police involvement in John's death? This incident has occured 2 months ago and no real investigation has taken place. Why do you think this was swept under the rug by authorities?
