Johannes Mehserle refused to say anything but police say they questioned the six other BART police officers who were on the scene and did little after Oscar was killed. BART police also say they "questioned" 21 people who witnessed the shooting. After their "investigation" BART police decided to make no recommendation on whether charges should be filed in the shooting.

While most people who kill people with witnesses are immediately arrested, Alameda DA Orloff had aid he didn't plan to charge Mehserle until the end of next week. This is despite several videos of the scene clearly showing Oscar was lying on the ground and that Mehserle shot him in the back. There are some suggestions that pressure on Orloff due to daily protests could cause him to respond sooner, perhaps even in the next few days. In the mean time, Mehserle is not just not in jail but is free to travel and even leave the country.
