In seriousness, if you are talking about stealing a public shield, lol theres no point in that to begin with, unless you were wanting to edit it.
If you are talking about stealing a private personal shield, I think thats more rude than stealing a head seeming as with shields you are actually able to choose between public/private. Honestly, private shields and swords should be removed (or lower price to 1000) since they can be stolen just as easily as heads.
