Sheriff's detectives have identified the contents of a letter left at the scene of last week's bombing of a patrol car. The letter quotes Adolf Hitler.

But investigators knew little else about the bomber."He's either a member of a radical faction or someone that wants us to believe they are," said Salt Lake County Sheriff's Capt. Bill Van Wagenen. "But I'm not sure of his motives."

On April 18, a homemade pipe bomb exploded and destroyed a marked sheriff's vehicle that was parked in the driveway of a sergeant's Murray home. Several pieces of the bomb were embedded into the side of the house from the explosion, but no one was injured.

Sheriff's officials were confused about a note that was found near the burned vehicle. Sheriff Aaron Kennard said the note did not make a lot of sense but implied that the bomber might strike out against a law enforcement officer again.

The note had a drawing of a hand grasping a sword. Next to it were the words "Aut Pax Aut Bellum." The drawing is apparently a Scottish clan symbol representing the clan of Gunn, and the words mean "either war or peace," said Sheriff's Lt. Sydney Elliott.

According to the book "Clans and Tartans of Scotland" by Robert Bains, the clan is noted for its "warlike and ferocious character" he said. Detectives learned about the history of the symbol and motto after a television viewer recognized the symbol.

Detectives asked University of Utah and Salt Lake Valley Community College professors to help them find the source of the two paragraphs contained in the note. Thursday, they determined that the words were taken from Page 533 of Hitler's "Mein Kampf."

Van Wagenen said even though the quotations are "nebulous," law enforcement officers are being cautious in case the note is an indication that the bomber will strike again.

"I feel there's a possibility that he could hit again, but I don't think it's imminent," the captain said. "Our men are taking added precautions where they're parking their cars and they're being more careful in general."

Other agencies, including Salt Lake police, are taking precautions too. "We've all been telling each other to watch out," said Salt Lake Police spokesman Sgt. Scott Atkinson.

Van Wagenen said, "We don't feel it was just us that was targeted. We feel it was us as a law enforcement agent."

Law enforcement officials from several agencies have planned another meeting on Monday to discuss the case.

"The lack of a great, creative, renewing idea means at all times a limitation of fighting force. Firm belief in the right to apply even the most brutal weapons is always bound up with the existence of a fanatical faith in the necessity of the victory of a revolutionary new order on this earth.

A movement that is not fighting for such highest aims and ideals will, therefore, never seize upon the ultimate weapon."
