During an appearance on WTOP's "Ask the Governor" program, O'Malley said, "Lots of people have seen the video, very few of us were actually there on the scene... I'm sure this matter will receive the attention it deserves from the police chief of Prince George's County."
The governor went on to say it's the responsibility of any police force to keep on eye on both the streets and the officers themselves.
"The most important thing that protects officers on the streets is the trust the public has in their integrity," he said.
O'Malley said he hasn't personally discussed the case with county officials, but said there has been communication between his office and local leaders on a staff level.
Four officers have been suspended since the video went public. The FBI is also conducting an investigation of its own to see if any civil rights were violated.
