Reply #6: It's an attractive proposition, but ultimately not practical

[Old School Liberal]

I believe our 10th Amendment specifically states that powers not specifically given to the federal government fall under the jurisdiction of the states or the people.
If memory serves, radio broadcast bands are not included, and thus, a national ban would be unconstitutional.

However, I do believe it was rather effectively applied in Germany, sometime in the 30s, if a hypothetical model were to be required.

I suppose if the loose constructionists have their way it can be applied, and if that is the case, I propose that these dangerous men (i.e. whomever you label) be banned from public streets and roads, as well--we may be guaranteed the right to move about, but certainly not a platform upon which to walk.
