“recognize that you only go into a full body search if you have some corroborating suspicions besides the dog.”
How about we NEVER authorize full body searches,,,,,ever. Would society really seriously lose much ability to do proper law enforcement?
Here in California, many dealers except pot carry their product in their anus or vagina. They know that law enforcement is not going to through all the trouble to do a search.
These would be the small street dealers not the big movers. However, the best way to get to the big movers is to catch the little people and then "roll them up" to the big ones.
