Is it even reasonable to believe this can be enforced without becoming a fiasco?
Of course it's not reasonable. This whole thing is a dog and pony show. At best, it is a hollow display of facile "patriotism" on the part of self-serving politicians. At worst, it will be used as a red herring law - enforced only to punish only those that displease the ruling elite, but who cannot be brought up on other charges.
The existing Federal Flag Code
already contains the following:
Sec. 4 (d) The flag should never be used as wearing apparel, bedding, or drapery.
(e) The flag should never be fastened, displayed, used, or stored in such a manner as to permit it to be easily torn, soiled, or damaged in any way.
(g) The flag should never have placed upon it, nor on any part of it, nor attached to it any mark, insignia, letter, word, figure, design, picture, or drawing of any nature.
(i) The flag should never be used for advertising purposes in any manner whatsoever. It should not be embroidered on such articles as cushions or handkerchiefs and the like, printed or otherwise impressed on paper napkins or boxes or anything that is designed for temporary use and discard.
(j) No part of the flag should ever be used as a costume or athletic uniform.
How often is any of the above enforced? On the basis of Sec. 4 (e), attaching a flag to the window of an SUV is a crime. On the basis of Sec. 4 (g), every "patriotic" website on the internet that uses the stars and stripes as a background or header is guilty of flag desecration. And on the basis of Sec. 4 (i), every Fourth of July picnic item on the market is in violation of the law - as is every business card or mailing label that includes a flag, not to mention almost every political campaign item in existence. And let's not even consider
the flag on door mats, coasters, and toilet paper!
This amendment is nonsense from start to finish - a waste of Congress's time and taxpayer money. How would you go about it?
