Frank Ocean -- NOT Pressing Charges Against Chris Brown

Frank Ocean says he WILL NOT press charges against Chris Brown after last week's parking lot brawl.

Frank wrote a post on his Tumblr page to explain his decision, saying, "As a child I thought if someone jumped me it would result in me murdering or mutilating a man. But as a man I am not a killer."

He continued, "I’ll choose sanity. No criminal charges. No civil lawsuit. Forgiveness, albeit difficult, is wisdom. peace, albeit trite, is what I want in my short life. Peace.”

As TMZ first reported, Frank and CB got into a physical altercation last week outside a recording studio in L.A -- allegedly over a highly coveted parking spot.
