CTI did the disguised weapons video back in the 90's for the National Sheriff's Assoc. This was done when a number of our Police where being killed or attacked with disguised weapons. Mainly during arrests when some of these disguised weapons where missed during initial searches. Officer safety is always a priority, this trailer of the training video does show some key points. CTI still does sell the video if you are interested.
