Because some of us love this country as a place in which every accused criminal gets due process of the law. Because some of us wish to keep this a place in which the accused are fairly tried for their crimes, rather than jailed and held with no charges pressed, or convicted without the right to defend themselves. Some of us see the scary way in which our country has gone due to the patriot act and understand the Constitution and the way the country works well enough to find it scary that we are holding people without trial, without formal charges pressed, and not allowing those individuals to seek legal counsel or contact the outside world.
If you wish to live under the kind of government you propose above-may I suggest Cuba? There are Cuban members of this board who would love to be there if it were not for the government, but your statement, lemondaisy, suggests you would like the governmnent as it is.
