Discussion Topic: Should You Have to Report a Lost or Stolen Firearm?

From CT.gov:

_Governor M. Jodi Rell has signed a bill to require gun owners to report their guns lost or stolen within 72-hours of discovering them missing.

“Right now, police are powerless if they trace a gun used in a crime back to its owner and the owner claims it was stolen,” Governor Rell said. “This law targets irresponsible gun owners in an attempt to stem the tide of stolen guns used in crimes in Connecticut. We think it will prove to be a useful tool for law enforcement by closing up a loophole in our laws.”_

Is this really a useful tool for law enforcement or just another way to target gun owners?
