Bounty hunters

ORLANDO, Fla. — In the roiling national debate over the shooting death of Trayvon Martin, one group has been conspicuously quiet: gun owners.

The National Rifle Association has not issued a statement, despite growing criticism of its part in advocating for legislation such as Florida’s "stand your ground" law — which has come under increasing fire in the wake of the unarmed teen’s shooting by Neighborhood Watch volunteer George Zimmerman.

But online, proponents of carrying concealed weapons are participating in forums that reflect their concerns over the touchy subjects of race, gun laws and the need for facts in the most controversial shooting in recent memory.
