Ah,
Of course, that brings up another issue; legally defining "descration"...
Every court in the country would be tied up trying to define it. Is it defined by whether you're saluting when you burn the flag? What about flag-clothing? An American Flag shirt is ok, but what if it's across the bottom of jeans?
I would love to see the exact wording of this proposed amendment.
Actually, if you read the U.S. Flag Code (which prescribes how to treat the American flag but has no criminal penalties attached), American flag shirts are illegal. So is incorporating the American flag or parts thereof into any article of clothing, except for uniforms of patriotic organizations. The latter would include, for example, the Boy Scouts, police, the military, etc., but would not include football teams, etc. I would think that Olympic teams would be exempt from that, as they represent the United States directly.
Yes, legally defining "desecration" would enrich a lot of lawyers.
