A 2005 image presentation by the LA County Sheriff's department on jail weapons and prison contraband. Credits to xxxxxxxx for finding it. This is taken from the White Car forum for those who don't have access to it - I assembled the pictures into an imgur album so it's not too hard to view. I strongly suggest you read through this, it provides a wealth of information on prison contraband. There are 37 images in total.
