Happy to see the owner will get back his belonging
Would have it been me (does that sentence even make sense? Sorry it's my French's side coming out

, I would be very thankful to Drakar who made this happen
While I do believe thieves should treated as such and agree with a lot of what has been said here, I wouldn't care as much about the thief as about the item itself, in that particular case
This doesn't need to become a lynch mob or witch hunt. The guy's is getting back his gun, the thief will probably think twice next time the thought occurs to him
