Just by having the gun in his possession he was guilty of the charge, and has no defence in law against it
Paul Clarke, 27, was found guilty of possessing a firearm at Guildford Crown Court on Tuesday – after finding the gun and handing it personally to police officers on March 20 this year.
The jury took 20 minutes to make its conviction, and Mr Clarke now faces a minimum of five year's imprisonment for handing in the weapon.
In a statement read out in court, Mr Clarke said: "I didn't think for one moment I would be arrested.
"I thought it was my duty to hand it in and get it off the streets."
I give up.
