To The Colors

"On June 14, Theodore Roosevelt was dining outside Philadelphia, when he noticed a man wiping his nose with what he thought was the American Flag. In outrage, Roosevelt picked up a small wooden rod and began to whip the man for 'defacing the symbol of America.' After about five or six strong whacks, he noticed that the man was not wiping his nose with a flag, but with a blue handkerchief with white stars. Upon realization of this, he apologized to the man, but hit him once more for making him 'riled up with national pride.'" See generally Wikipedia (internal citations ommitted); cf. 36 USC §110.

From the Flag Code:

• When the flag is displayed from a staff projecting from a window, balcony, or a building, the union should be at the peak of the staff unless the flag is at half-staff. When it is displayed from the same flagpole with another flag, the flag of the United States must always be at the top except that the church pennant may be flown above the flag during church services for Navy personnel when conducted by a Naval chaplain on a ship at sea.
• When the flag is displayed over a street, it should be hung vertically, with the union to the north or east. If the street runs north-south, the stars should face east. For streets running east-west, the stars should face north. If the flag is suspended over a sidewalk, the flag's union should be farthest from the building and the stars facing away from it.
• When flown with flags of states, communities or societies on separate flag poles which are of the same height and in a straight line, the flag of the United States is always placed in the position of honor—to its own right. The other flags may be the same size but none may be larger.
• No other flag should be placed above it. The flag of the United States is always the first flag raised and the last to be lowered.
• When flown with the national banner of other countries, each flag must be displayed from a separate pole of the same height. Each flag should be the same size. They should be raised and lowered simultaneously. The flag of one nation may not be displayed above that of another nation in time of peace.
• The flag should be raised briskly and lowered slowly and ceremoniously.
• Ordinarily it should be displayed only between sunrise and sunset, although the Flag Code permits night time display "when a patriotic effect is desired." Similarly, the flag should be displayed only when the weather is fair, except when an all weather flag is displayed. (By presidential proclamation and law, the flag is displayed continuously at certain honored locations like the United States Marine Corps Memorial in Arlington and Lexington Green.)
• It should be illuminated if displayed at night.
• The flag of the United States of America is saluted as it is hoisted and lowered. The salute is held until the flag is unsnapped from the halyard or through the last note of music, whichever is the longest
