As technology companies compete in this new market, the lesson for the burgeoning Homeland Security industry is clear: There are many opportunities for those who are prepared to do some forward thinking and bring to bear privacy considerations during the design and development of their products and services.

People of good faith and good conscience can debate the pros and cons of many things being done in the name of Homeland Security. And without a doubt, that debate is a vitally important discussion for us all to be engaged in, because the very future of American democracy may hang in the balance.

But in the meantime, we will all need to live with the realities of this new security conscious era. And we all will have a vastly easier time of it if the creators of security-enhancing technologies gave some thought along the way about how to respect the privacy of those whose security they are charged with protecting.

Today's Homeland Security entrepreneurs can, if they heed the lessons of the not-too-distant dot-com past, build products and services that meet the needs of law enforcement and citizens' rights. When privacy gets a seat around the drawing board, the innovations that arise can protect and preserve both our democracy and our economy, ensuring both prosperity and domestic tranquility.
