Uk if you found a gun somewhere could you keep it?

Well I am sure it fired at one point so yeah definitely keep it, Im sure its not a murder weapon or anything like that, I mean its really normal to find a gun buried in the ground, come on man, throw it out!!!!! One the person that buried it probably doesn't want anyone to find it and depending on who it belonged to you might not want that kind of trouble, even if you turned it into the police, it could have been the police or other special forces that buried it in the first place so I would get rid of it.
