The thing is, a "law" in science is not absolute. It is just a very succesful theory. This is an extremily misunderstood concept.
For instance, Gravity is only a theory. Yup, its been around several hundred years, and it seems absolutely obvious. We can use Newton's theory (often called "Law" because it is well-established) of gravity to explain the trajectory of a rifle bullet, the dropping of an apple, the motion of the planets and fly a spaceship to the moon. The only problem is, IT IS WRONG.
Actually, the "Law of Gravity" they teach in high school is only a special case. It works just fine on medium to large size scales ( larger than molecular dimensions) and slow (relative to light) speeds. Einstein's Theory of Retivity tweaked the THEORY of gravity in the early part of the century, and now the theory encompasses pretty much everything except extremily small scales. In fact, the major problem in physics these days is marrying the theories of Quantum Mechanics (behavior of really small stuff) and General Relativity (behavior of really big stuff). Note that Evolution has also been tweaked similarly, and ID proponents generally use this as "evidence" that the theory is flawed or wrong.
Quantum Mechanics and General Relativity are THEORIES that allow the most accurate predictions about the natural world in the history of Mankind. Yet, neither of these theories is "proven" because it is absolutley impossible to prove something; it is only possible to disprove it. This is a fact that is central to science. The problem arrises in that the general public doesn't understand this and assumes if a scientist says it, its a fact. Then again, this isn't all that surprising given the declining quality of our schools.
So, when people say we should teach Intelligent Design along side Evolution because Evolution is only a theory (ID isn't, as someone else pointed out), I'm all for it. I'd also like to start teaching some other intelligent design-based science classes. For instance the Maxwell's laws (again, only a theory!) are over a hundred years old and basically gave humans the ability to control electricity. However, because these "laws" are really only theories, I think we should also theach the theory that electrons acting under a potential field are not what makes electricity work, its actually angels dancing through those copper wires. Sure, its not testable, it has no evidence to support it, but I can think of it and thats all that is necesary to put it on equal footing with the mere theory of electricity.
I mean, come on, what could be the possible consequences of tossing half a millenium of scientific progress out the window on a whim? Its not like this country has exported all its manufacturing capability and is now dependant on an information/technology based economy. I'm pretty sure torpedoing the education of the already-entitled-and-not-too-bright latest generation bodes very well for the future of our country. I'm certain that if enough priests get together, they can pray for the "intelligent Designer" to extend the internet for us, build faith-based computers and intelligently design the next genereation of antibiotics to combat those pesky resistant strains of bacteria which oddly enough only appeared after we started using antibiotics on them.
Seriously though, I'm not trying to offend any religeous folks out there. I'm just trying to point out that religeon has had a long history of going against the the grain on scientific matters, and it doesn't have a very good record of winning. Leave science to the scientists, thology to the theologians and please, please don't mess up the schools any more than they already are.
