Congressmen Stevan Pearce, along with Rep. Peter King and Rep. Bill Shuster, introduced a bill today that would protect those who come forward to report suspicious activity from frivolous civil liability prosecution.

If passed, the bill, known commonly as the 'John Doe' protection legislation, would grant immunity to anyone who alerted transportation security to actions believed to be threatening or to any personnel that "takes reasonable action to mitigate such activity."

"We cannot have Americans thinking twice when it comes matters of national security," said Congressman Pearce. "If a passenger sees something threatening, they should report it immediately and do so without the specter of potential prosecution hanging over their head."

"Alert Americans are often our first and last line of defense in protecting the country from terrorist attacks. They should not face potential prosecution for doing the right thing and coming forward to report suspicious activity.

"It is a sad commentary that this kind of common sense has to be written into law, but we must make it clear to America's enemies that they can not exploit our system of justice."...

We've all seen this phrase in block letters: "REPORT SUSPICIOUS ACTIVITY," followed by a 1-800 number. But if a House Democrat manages to kill a tipster-immunity measure under consideration in Congress this month, people who report suspicious behavior could be sued in civil court if the accused are not charged with a crime. November's frightened U.S. Airways "John Doe" passengers in Minneapolis are already in the crosshairs.

The lawmaker in question is Bennie Thompson, chairman of the House Homeland Security Committee. He thinks that granting tipsters immunity amounts to racial and religious profiling. Yes, that's the Democrats' "homeland security" pointman in the House speaking.

For two months, Mr. Thompson has deployed the profiling argument against this measure, tucked into the House transportation-security bill. The good news is that a bipartisan House majority already passed it 304-121 seven weeks ago. But sadly, Mr. Thompson is expected to strip it from the bill. He is expected to be the lead House negotiator in the coming weeks when the bill reaches conference committee, and if he is, he will have considerable sway over the final product...
