Spray-painting 'Kill all police' on a public wall doesn't rise to the level of a terrorist threat, a Detroit judge ruled Tuesday.

Stuart Lewis, 49, of Detroit, faced a series of charges after police pinpointed him as the culprit who painted anti-police graffiti on a wall last October.

After discovery of the graffiti threats, Detroit Police Chief James Craig vowed to find and arrest whoever was responsible.

The department followed through, dispatching its Special Response Team -- the equivalent of SWAT -- to arrest Lewis at his home.

The man's dog was killed during the raid.

"I believe that level of force was necessary, given what we knew," Craig said after the arrest.

Police also found marijuana while making the arrest.

The Wayne County Prosecutor's office charged Lewis with threat of terrorism, delivery or manufacture of marijuana and malicious destruction of a building.

Wayne District Judge Deborah Lewis Langston ruled there wasn't enough evidence to support the threat of terrorism charge. The charge was dismissed.

Lewis also faces charges of felonious assault and felony use of a firearm for an Oct. 17 incident in which he's accused of using an air gun to threaten a man who was attempting to repossess Lewis' car.

Craig has aggressively sought the arrest and prosecution of suspects accused of making threats against police. He became frustrated by the county prosecutor's reluctance to issue charges in one series of cases and presented numerous police-threat cases instead to state Attorney General Bill Schuette in July.

Lewis is expected to be arraigned on all remaining charges in Wayne County Circuit Court Dec. 20.
