Allen's lawyer, Sawyer Smith, tells TMZ Sports ... Allen wants to make sure no other citizens go through the horrible experience he did, that's why he's chosen to sue.
Smith, who has sent a letter of intent to sue to Fort Meyers Police, saying "he's a fighter, and he's going to stand up for this community and its residents to have a fair shake when they interact with law enforcement."
Allen was cleared of any wrongdoing last month after he was arrested for allegedly driving around while pleasuring himself. Cops eventually realized they had the wrong man and let him go.
Stay tuned.
