Shuwail worked in the Libyan police forces.
In October 2012, Shuwail was nominated for minister of interior by prime minister Ali Zeidan
. However, the High Commission for the Application of Standards of Integrity and Patriotism that evaluated the suitability of nominees declared that four nominees, including Shuwail, did not endorsed him as interior minister.
However, at the beginning of December 2012, he won the case against the verdict of the commission and was officially appointed as minister.
On 21 May 2013, Shuwail resigned from office for "personal reasons".
Mohammed Khalifa Al Sheikh replaced him in the post on 26 May 2013 after the Libyan congress approved him.
