(CNN) -- Recently, a federal judge blocked the enforcement and implementation of the indefinite military detention authority that Congress passed late last year as part of the 2012 National Defense Authorization Act. It's a welcome sign from our courts that constitutional safeguards still exist.  When this provision was debated last year, we argued that it was an unwise expansion of law that jeopardized the freedoms of all Americans. We were heartened that the court has wisely chosen to block this policy for much the same reason we opposed it.  However, this federal court injunction is only temporary, and the debate over whether the military has the authority to indefinitely detain individuals captured on U.S. soil without trial is far from over.  Earlier this year, we introduced legislation, recently co-sponsored by U.S. Rep. Justin Amash, R-Michigan, that would require that civilian law enforcement, including the FBI and civilian courts, take the lead with respect to those captured or detained in the United States.  Some, however, have argued that this approach to national security -- one that involves law enforcement and not solely the military -- is tantamount to ceding ground to al Qaeda. This argument, designed to paint members of Congress as "soft on terror," is wrong on two fronts.  First, enemies who want to attack us on our native soil -- particularly would-be suicide bombers -- do not intend to be captured and are not lured to America by the identity of their potential jailer or prosecutor. The strange assertion that our civilian courts and law enforcement system serves as an incentive for terrorists to come to America ignores the terrorists' true motivations.  The question of civilian versus military authority is irrelevant to our enemies. It is, however, incredibly important to protecting Americans' constitutional rights and freedoms while still allowing us to effectively fight terrorism.  Second, our civilian law enforcement and justice system have worked exceptionally well in prosecuting, convicting and jailing dangerous terrorists. To say that the military is the only institution up to the task is an unfair indictment of the valiant work done by the men and women who have kept us safe since 9/11.  We have convicted hundreds of terrorists in our federal civilian courts, with many of them incarcerated at the "Supermax" prison in Florence, Colorado. Yet military commissions in Guantanamo Bay have only resulted in seven convictions, and two of those terrorists have already been released.  As Congress works to update our national defense policy and the courts continue to weigh the implications of allowing indefinite military detention without trial, we remain committed to defending our country from those who seek to do us harm, both abroad and here at home.  The debate over protecting constitutional liberties alongside our counterterrorism efforts is not now and has never been an issue of rewarding terrorists -- just ask any inmate at Supermax.  Rather, as Defense Secretary Leon Panetta, FBI Director Robert Mueller and Director of National Intelligence James Clapper advocated during last year's debate, it's about giving our law enforcement community the maximum ability to protect us within our constitutional system. This is a system that guarantees freedom and liberty to the American people alongside their safety and security.  Inviting our armed forces into our cities and towns with the power to indefinitely detain Americans without trial is a misguided attempt that erodes our rights to due process and limits the effectiveness of civilian law enforcement.  This approach also would unnecessarily burden our military with a responsibility it does not want and, most importantly, does not make us safer.

Sen. Mark Udall and Rep. Adam Smith say a judge was right to block a law that allows indefinite detention of terrorism suspects caught on American soil
